2.1.

Presentation of the Program DOC is the ABB program for drawing and calculating single-line diagrams of low and medium voltage electrical plants, for selection of the switching and protection devices and for verifying coordination of the protections. DOC is aimed at all professionals in the electrical sector looking for a precise but simple and rapid tool, which helps them to do their work. The main functionalities of the program are:  Drawing the single-line electric diagram.  Drawing the key diagram of the auxiliary circuits.  Calculation of line current and voltage drops.  Calculation of short-circuit currents.  Dimensioning low and medium voltage cables.  Dimensioning switching and protection devices.  Switchboard configuration  Calculation of overtemperatures in ANS switchboards.  Setting and coordination of protection devices.  Verifying cable protection.  Printing the single-line diagram and project documentation.

The program can calculate electric networks with the following characteristics:  Medium voltage: Vn ≤ 36kV 50/60Hz State of the neutral: Insulated / Compensated  Low voltage: Vn ≤ 1kV 50/60Hz Three-phase power supplies with and without neutral, two-phase and single-phase Distribution system : TT – TN-S – TN-C – IT       

Unlimited number of levels and departures. Several distribution systems in the same network Three-phase networks with single-phase and two-phase loads Plants with service generator. Plants in cogeneration. Plants with back-up transformers. Island operation, without restrictions on the number of generators.

Colors of the Single-line Diagram To help in reading this document, the images of the single-line diagram have – where possible – been made with a white background and therefore with a configuration of colors different from the one predefined in the program. To use the program it is advisable to use the predefined colors (black background and green, yellow or red symbols according to their state). Further clarifications about color management are available later in this document.

3.1.

Profile Selection DOC can be used either in the Light or Professional Profile according to requirements, combining calculation precision with rapidity of project execution in the best way. The Light Profile, with simple and immediate use, is recommended for drawing diagrams and doing calculations with a low level of complexity and with low voltage or schematized supply by means of a MV/LV transformer. On the other hand, the Professional Profile, which makes all the DOC functionalities available, is recommended for drawing and calculation of complex diagrams with medium voltage supply or with supply by means of generators. On program start-up, the window for selection of the Profile to use DOC with is shown.

Window for Profile Selection

Deactivate / Reactivate the Window for Profile Selection. Profile selection can be deactivated by choosing the “Do not ask again on start/up” option. In this case DOC will start up with the last Profile selected. Profile selection can be reactivated from the Tools – Options… menu.

DOC – User Manual - Page 11

3.2.

Plant General Properties The plant general properties window allows you to define the type of plant to be made. The window is available in simplified mode (Light Profile) and in advanced mode (Professional Profile). In both cases it is possible to select the type of supply at the top, whereas in the lower part the parameters common to the whole single-line diagram are defined.

Plant General Properties – Light Profile and Professional Profile LV Distribution This is the supply suitable for representing civil, service sector plants or small-sized industrial applications. The parameters required to define the supply are the three-phase short-circuit current or the three-phase fault impedance value or of the short-circuit apparent power.

Page 12 of 170

“LV Supply”: representation in the single-line diagram Trafo MV-LV This is the supply suitable for representing medium-large power plants when it is not necessary to coordinate the protections between the MV side and the LV side of the transformer/s. It is also useful for verifying the voltage drop from the transformer secondary to the last load (without considering the voltage drop inside the transformer which would be counted by DOC if the “Transformer with 2 windings” Single Object was used). The parameters needed to define the supply are the number, the rated power and the rated short-circuit voltage of the transformer/s. MV Supply This is the supply suitable for representing the medium voltage section in a large-sized plant as well, selecting the MV side switching and protection devices and coordinating them with the LV side of the plant. The parameters needed to define the supply (normally communicated by the power utility company) are:  The rated voltage.  The short-circuit current.  The ground fault current at the point of delivery.  The state (insulated / compensated) of the neutral. The calculator-shaped button allows input of the short-circuit current value in an alternative way, when the three-phase fault impedance or the apparent short-circuit power are known. It is also possible to personalize the short-circuit power factor value (needed for calculation of the short-circuit current peak value). Finally, input of the ground fault current value in an alternative way is possible when the capacity to ground or the Petersen coil parameters are known (only in the case of compensated neutral).

“MV Supply”: representation in the single-line diagram Generator This is the supply suitable for representing plants totally supplied in an island, such as ships or off-shore platforms. To define the supply it is sufficient to indicate the rated voltage value of the generator. Subsequently it will be possible to define the generator with all its parameters or to select it from the list of those available in DOC.

Selection of the “Generator” Supply The “Generator” supply must not be used in the case of cogeneration or service generators (Cf. Chapter 4.5) In these cases it is advisable to use another of the supplies available and subsequently represent the generator by means of the “Generator” Single Object.

“Generator”: representation in the single-line diagram

Panel for “Setting LV section parameters” The panel allows the preset value for the main parameters characterizing the LV section of the plant to be defined. Precise setting of the parameters means the drawing and data input stages can be speeded up. Parts of the plant which must have different parameter values (for example, you select Phases = LLLN, but you also have to represent single-phase loads) can be customized afterwards during drawing (Cf. point 3 of Chapter 4.2)   

Rated voltage: a list of the standardized voltages is available. In any case, it is possible to manually digit a value between 0V and 1000V as you want Distributed phases: all possible combinations in a three-phase system are available (LLLN, LLL, LLN, LL, L1N, L2N, L3N) Distribution system: TN-C, TN-S, TT and IT distribution systems are available. It is advisable to set the distribution system of the supply. Indications are given below about how to proceed in the case where there are plant sections present with a different distribution system (for example, sections managed with the TN-S system in plants with TN-C supply)

Rated frequency Selection of the number of poles according to the distributed phases: It is possible to indicate your own preferences to DOC regarding management of the neutral in LLLN and LN circuits. Selection of the reference Standard for miniature circuit-breakers: DOC is able to select the modular protection devices according to the correct product Standard according to the type of plant. In particular, for industrial plants, the nameplate values declared according to the IEC 60947-2 product Standard are used, whereas for plants in the civil/service sector, the nameplate values declared according to the IEC 60898 product Standard are used Automatic optimization of the neutral: when active, DOC proposes the neutral of the cables with sections equal to 50% of the phase section (only under the conditions permitted by the Standard!). Otherwise the neutral conductor has a section the same as that of the phases.

Panel for “Plant loads” After calculation of the single-line diagram drawn, the plant load data are given in this panel in terms of:  Active power  Reactive power  Current  Power factor

Page 16 of 170

Advanced settings Further advanced level settings are available which are already predefined with values that do not normally need to be changed. The advanced settings are always visible if you use the Professional Profile. When using the Light Profile, you can access them by pressing the “Advanced settings” button. The advanced settings provided are:  Selection of the Standards for the short-circuit calculations between: o IEC 60909 (International Standard for 50-60Hz applications) o IEC 61363 (Naval Applications) o NFC 15-100 (French Standard) o VDE 0102 (German Standard) o Method of the symmetrical components.  Selection of the Standard for dimensioning low voltage cables among: o CEI 64-8 (Italian Standard) o IEC 60092 (Naval Applications) o IEC 60364 (International Standard) o UNE 20460 (Spanish Standard) o VDE 0298-4 (German Standard) o NFC 15-100 (French Standard)  Temperature: ambient temperature value (used for calculation of switchboard overtemperatures) and the one inside switchboards (presumed or calculated by DOC; used to consider any temperature derating in of the performance of the protection device)  Protection of people: contains the parameters used by DOC to verify protection against indirect contacts: Contact voltage; Tripping time; Resistance of the ground plate (cf. Chapter 6.1.1 for a description of their use).  Automatic selection of the type of circuit-breaker: data to guide DOC in selecting Miniature, Molded-case or Air circuit-breakers according to the current.

3.3.

Layout Selection Once the general plant properties have been defined, DOC allows the layout to be used to be defined among the following types:  “MV columns” (recommended for drawing diagrams of MV compartments)  “LV columns” (recommended for drawing LV plants)  “Free” (recommended for producing extremely customized and/or special diagrams on A2, A1, A0 page formats) To make selection easier, a preview is available of all the possible layouts.

Previews of the “MV columns”, “LV columns” and “Free” layouts

Changing the Layout during Diagram Drawing During drawing of a diagram, it may be necessary to change the layout in relation to the one selected previously (for example, “MV columns” on the first page and “LV columns” on the following pages). This is possible by using the “Change layout – page dimensions” command in the “View” menu. The “Change layout – page dimensions” icon

Page 18 of 170

is available in the “View” toolbar.

3.4.

Main Window (1) Menus and toolbars In this area there are the commands used for managing files, the commands for drawing and the program functionalities. (2) Macro Objects The Macro Object area contains all the macro-blocks, i.e. blocks consisting of several Single Objects, which allow rapid diagram drawing. The contents of this area are contextual to the type of diagram you are drawing (MV, LV or of the auxiliaries). (3) Drawing sheet This is the area where the project to be made with DOC takes shape. It is the page, complete with layout, just as it can be printed to document the project. (4) Work flow The “Work flow” toolbar has the aim of guiding the user during the main stages of carrying out the project.

DOC work Area The work flow, from which the name of the relative Toolbar comes, to be followed to work best with DOC, is as follows: 

Personalizing the Main Window The appearance of the main window of DOC can be customized by changing the colors of the diagram and the presence and position of the toolbars. This way you can work in a way closer to your own habits.

Colors To change the colors, use the “Preferences…” command in the “Tools” menu. The settings are on the “Colors” page. The colors which define the state of the Single Objects can be changed, as well as the work sheet background color.

Window for personalizing the colors The profile of the colors preset in the program have the following meanings: Color Meaning Yellow Single Object to be dimensioned or checked Green Single Object dimensioned correctly Red Single Object with problems or errors Brown Single Object not supplied in the present network configuration

Toolbars The Toolbars can be enabled – disabled by the “Toolbars” command in the “View” menu. It is also possible to move the Toolbars into your favorite position of the work environment by dragging them with the mouse. Visibility of the Macro Objects bars is a function of the active work flow button. Their position can be customized in the same way as the other Toolbars.

4. Drawing the single-line diagram This chapter describes:  drawing the single-line diagram of Low Voltage networks;  drawing the single-line diagram of Medium Voltage networks;  network data input;  managing several power supplies in the same project. After reading this chapter, the user will be able to:  use the Single Objects and Macro Objects to draw the single-line diagram of Medium and Low Voltage networks;  draw all types of diagrams, even those consisting of several switchboards and shown over several pages;  define the characteristics of loads and lines;  configure networks supplied by a power supply and by back-up generators.

DOC – User Manual - Page 21

4.1.

General indications on the drawing Once the general properties of the plant and the layout have been defined, the utility symbol is already present on the drawing sheet. You can therefore proceed to draw the single-line diagram as described in this chapter. It is possible to use two different types of objects with DOC:  Single Objects  Macro Objects The Single Objects are the blocks which represent a single element of the electrical plant and which allow a single-line diagram to be made (for example: “LV Circuit-breaker”, “LV Cable”, “Generic load”, “Busbar”, “Motor”, …). By connecting the Single Objects with each other, you can obtain infinite combinations for representing any type of plant. The icons of the Single Objects are found in the Toolbars area. On the other hand, the Macro Objects are a combination of several Single Objects already ready to be drawn with a single click. The Macro Objects thereby allow you to draw much more quickly, at the expense of the variety of plants which can be shown. Furthermore, with the Macro Objects it is only possible to draw purely radial networks, whereas the Single Objects allow meshed type networks to be made which DOC is able to manage during the calculations. The best result is obtained by combining the Single Objects and the Macro Objects, combining the need of each particular plant with the speed of making the diagram. To draw a Single Object or a Macro Object, it is sufficient to click over the icon that represents it. The Single Object or the Macro Object will be hooked up to the mouse pointer, ready to be drawn with a click of the left button in the desired position in the diagram. The Single Objects are only available with the Professional Profile.

The Medium Voltage Single Objects and the Medium Voltage Macro Objects are available using the Professional Profile and starting a network with the “MV Supply”

4.2.

Drawing with Macro Objects This chapter describes how to make a single-line diagram only using Macro Objects. The Macro Objects are useful to make a single-line diagram rapidly, starting from the main device and going on with the departures on the load side until the loads are reached. The program automatically verifies congruence of the single-line diagram.

Page 22 of 170

Low Voltage Macro Objects

“General” and “General Second level” Macro Objects

“Generic departure” and “Motor departure” Macro Objects

1) Start positioning the main circuit-breaker by selecting the “Main CB with Overload and Short circuit protection” icon from the “General” Macro tools toolbar. The program will see to stretching the connections so as to take up all the space available both vertically and horizontally on the work sheet.

1) Main CB with Overload and Short circuit protection 2) From the “Generic departure” Macro select the type of feeder to be shown, for example, a “Generic Load feeder, CB with Overload and Short circuit protection + RCB” departure. Hook the Macro Object up to the barring on output from the main circuit-breaker. 3) The departure line is now connected to the barring and the program shows the dialog window for fast definition of the feeder data. This way it is possible to define the main data of the feeder while drawing:  Phases (single-phase, three-phase with and without neutral)  Distribution system  Description of the departure (to allow more flexibility, these are available on two lines)  Consumption of the generic load (rated current or rated active power and power factor)  Length and type of cable

DOC – User Manual - Page 23

3) Feeder properties fast input window To disable the panel for fast definition of the feeder, remove the checking off sign at the “Always show” option. Disabling these functions is useful for those who want to edit the data of a feeder in detail. The panel can be re-enabled from the “Toolbar” menu – “Preferences…”, on the “Other” page.

Phases and Distribution system The phases and distribution system properties must be consistent in the plant. This does not mean they must necessarily be the same throughout plant, but that there are rules which DOC helps you to follow (in fact, it is possible, for example, to manage sections of plant with a TN-S or TT distribution system starting from a TN-C supply, or single-phase lines derived from a three-phase system with neutral; but it is not possible, for example, to derive a single-phase load from a three-phase distribution without neutral or to derive an IT system from a TN system without using an insulation transformer which separates the two parts of the plant). DOC helps the user by only showing the properties compatible with the type of distribution selected. In the case of incongruence, DOC notifies the incorrect situation during the calculations and indicates the Single Objects by changing their color (Cf. Chapter Error! Reference source ot found.).

Page 24 of 170

Modifying the phases and distribution system Modifying the phases and distribution system can be done in two ways:  By selecting just one Single Object to be modified, applying the “Properties” command (the same as a double click over the symbol of the Single Object) and modifying its Phase and/or Distribution system properties (DOC will only show the values compatible with the position the Single Object occupies in the plant).  By selecting several Single Objects to be modified and using the “Properties” command, in the “Edit” menu. You can change the common properties with the “Common properties” window. 4) Once the main data has been defined, DOC adapts the feeder line in height according to the layout, occupying all the space available.

4) Final appearance of a feeder line 5) Repeat the procedure for every other feeder line.

Advice on Drawing in Columns There are two important rules to follow to improve the result of a drawing in columns:  The Macro Objects must be inserted in the center of the column. DOC helps to do this correctly thanks to the predefined (and unalterable) grid step, with the horizontal and vertical lines which intersect in the cursor position and follow it in its movements and with the same structure as the layout in columns.  Do not insert two Single Objects of the same type in the same column (for example, two “Circuit-breaker” Single Objects): the layout would not be able to host the data of both!

DOC – User Manual - Page 25

Coding the Single Objects DOC automatically codes the Single Objects according to the type of layout:  In the layout in columns, the coding follows the rule: Page.Column. Other Single Objects drawn in the same column will have the same numbering (Circuitbreaker –QF1.1; Cable –WC1.1; Load –L1.1).  In the free layout, the Single Objects of the same type will have incremental coding. The fifth circuit-breaker inserted from the start of the drawing will have the code “–QF5”; and could be combined with the third cable “-WC3”.

4.3.

Examples

4.3.1.

Switchboard with Sub-levels With the Macro Objects it is also possible to draw several levels in the same switchboard (for example, several thermomagnetic devices subordinate to a single residual current device). 1) Starting from the switchboard already defined in chapter 4.2, add a “Main second level residual current CB” Macro Object in the first free column from the “Main second level” Macros. The special barring will be added directly on the load side of the main second level device.

1) Main second level residual current circuit-breaker 2) Select the type of feeder to be shown from the “Generic feeders” Macros, for example a “Generic Load feeder, CB with Overload and Short circuit protection”. Hook the Macro Object up to the barring on the load side of the residual current device.

2) Feeders protected by thermomagnetic device

DOC – User Manual - Page 27

4.3.2.

Switchboard over Several Pages When a switchboard requires more space than the 11 columns available in the layout, the procedure described in this chapter can be followed to show it over several pages. 1) After having drawn the part of the switchboard which can be shown on the present page, add the “Line departure” Macro Object from the “General” Macros to the barring.

1) Board with link to page 2) Add a new page to the project with the “Add Page” command, available in the “View” menu (or click over the icon on the left) The settings of the current page, are also kept for the new page. Chapter 9.4 describes the settings available and how to change them should the new page require this.

Page 28 of 170

3) On the new page, add the “Line with arrival link” Macro Object from the “General” Macros. The pointer of the mouse must be positioned so as to fall half-way down the first column. Once the barring has been added, DOC will ask which “Departure line link” to connect it to among those available. The “Departure line link” sign follows the Page.Column format. In the case of an underlying image, the arrival line page link will be connected to link 1.11. A description can be added to improve recognition of the links.

3

Dialog window to connect the “Link to page” 5) The line on the new page has been added. Now it is possible to continue drawing the board on the new page!

Browsing through the Project Pages When the project consists of several pages, it is possible to browse through these using the “Next page” and “Previous page” commands in the “View” menu. The commands can also be carried out using the F12 and F11 function keys or by clicking over the icons shown on the left.

DOC – User Manual - Page 29

4.3.3.

Diagram with More than One Distribution Board If the plant foresees several distribution boards, these can be drawn in a single diagram with DOC. A network consisting of dozens of boards and hundreds of circuit-breakers and cables, can take up a lot of the processor resources and require long processing times. Should the calculation times become long, it is advisable to divide the project into several files. This is possible by simulating a board with a single generic load of equal power, net of the demand factor, and putting the board removed back into a new file. Simulate the network on the supply side in the new file by setting the supply data, copying the results of the calculation, voltage and short-circuit current of the original project.

1) A sub-board which supplies some feeders can be derived from the main distribution board. The line from the main distribution board to the sub-distribution board is drawn by means of the “Feeder line to sub-board…” Macro Object in the “Main feeders” Macro toolbar. The user can select the type of protection device to be used.

Feeder lines for sub-board 2) Add a new page as shown in the previous example. 3) On the new page, draw the “Arrival line link” Macro Object from the “General” Macros toolbar. The pointer of the mouse must be centered half-way down the first column of the layout. The program will ask to connect the Macro Object to the relative “Departure line link”.

Modifying the Drawing This chapter describes the most useful commands for modifying the single-line diagram drawing. All the commands are available in the “Edit” menu. Zoom In, Zoom Out and Pan with the mouse The “Zoom In”, “Zoom Out” and “Pan” commands can be given using the mouse wheel: this way the relative part of the diagram can be displayed rapidly with the right level of detail. The “Zoom In” and “Zoom Out” commands are, respectively, turning the mouse wheel upwards and clinking downwards. The “Pan” command is obtained by keeping the mouse wheel pressed and dragging the page. Multiple selection by means of selection box To select several Single Objects it is advisable to:  Disable any active command by pressing the “Esc” key.  Click over an empty point of the drawing.  Create a selection box which touches or completely includes the Single Objects to be selected. The selection will consist of all the Single Objects touched or completely included in the selection box according to the first click and to the direction in which the Single Objects are selected.  If the first click is on the right of the Single Objects to be selected, DOC will add all the Single Objects touched by the selection box to the Multiple selection.  If the first click is on the left of the Single Objects to be selected, DOC will add all the Single Objects completely included in the selection box to the Multiple selection. Multiple selection by means of clicking over the Single Objects to be selected A multiple selection can be created by clicking over each Single Object you want to add to the selection list. Once all the Single Objects wanted have been selected, select the Command you want to apply (for example, the “Properties” command) Duplicate The “Duplicate” command allows a Single Object or a Multiple selection of Single Objects to be copied onto the same page of the drawing with just one command. The predefined values of the original Single Objects will be copied into the duplicated Single Objects. Copy – paste The “Copy” and “Paste” commands allow a Single Object or a Multiple selection of Single Objects to be copied onto different pages of the drawing. The predefined values of the original Single Objects will be indicated in the pasted Single Objects. Stretch The “Stretch” command allows the length of “Busbars” and “Connections” to be modified.

Connections stretched using the “Stretch” command Add a text To add the text notes to the single-line diagram, use the “Text” command in the “Tools” menu.

4.7.

Labels The Labels are texts associated with each Single Object which allow the characteristics and calculation results to be displayed, such as the Iz of a Cable, the Description of a Circuitbreaker or the short-circuit current at a Busbar. The position of the Labels depends on the layout. Layout in columns The layout in columns shows all the data relative to a Single Object in the layout underlying it. The contents of each compartment of the layout is explained in the caption at the bottom on the left. It is not possible to modify the layout and results displayed.

DOC – User Manual - Page 41

Layout: Caption (first column on the left); data of a dimensioned feeder (green color) and data of an undimensioned feeder (blue color) Free Layout The free layout shows some calculation results in the labels placed beside each Single Object.

Labels in a free configuration diagram; Window for Label Management

Page 42 of 170

Label Management The Labels show the user the main data of each Single Object. The Labels can be customized:  The list of data contained in the Label can be changed by the user with the “Label Management” command in the “Edit” menu. There are two predefined Label configurations: one for the free diagram, the other for the layouts in columns. Special Label configurations can be saved to then be used again in other projects.  The fixed text part of the Labels can be changed by the user with the “Edit object labels” command in the “Edit” menu.

Code of the circuit-breaker modified with the “Modify labels” command Move the Labels Using layouts A3, A2, A1 or A0, which allow free drawing of the single-line diagram, the labels are shown beside the Single Objects. When two or more labels are overlaid, it is possible to move them with the “Move labels” command. Modify the data shown on a Label To modify the list of data shown on a Label, the “Label Management” command in the “Edit” menu is used.

DOC – User Manual - Page 43

Window for label management The window for label management allows definition of which properties to display in the diagram. To modify the state of a property, first select the Single Object to be modified in the “Object” menu, then you can enable or disable a property on the list of “Properties”. The selection effects all the Single Objects in the single-line diagram. Furthermore, it is possible to save a label configuration by means of the “Save configuration…” button, to be able to use it again in another project. The “Board configuration diagram” and “Free configuration diagram” options refer to the two types of layout:  “Board configuration diagram” is the layout in columns, available in two variants: one for LV plants and one for MV switchgear.  “Free configuration diagram” is the layout without columns, where the labels are displayed beside each Single Object. Example of using label management: Display\Hide the padlock The padlock icon (Cf. Chapter 5.5) present in the Labels is used to make the Single Objects, which have been locked by the user and that DOC cannot modify following a calculation, recognizable. The symbol is very useful during design, but cannot be used during the printing stage. It can therefore be useful to know how to manage the Labels to show or hide the padlock icon according to the task you are carrying out. This situation can be managed with two label configurations:  With padlock  Without padlock 1) Launch the “Label Management” command from the “Edit” menu 2) Select the “Switchboard configuration diagram” or “Free configuration diagram” option according to the layout being used 3) Activate the padlock for all the Single Objects. The padlock is managed by the “STATE” properties.

Page 44 of 170

Label management: STATE label of the LV circuit-breaker 4) Save the configuration with the “Save configuration…” button, assigning it whatever name you like. 5) Disable the padlock for all the Single Objects. 6) Save the new configuration as described in point 4). 7) To display of the padlock, launch the “Label management” command from the “Edit” menu, select the type of diagram used, switchboard or free, select the configuration where display of the padlock is foreseen from the pull-down. 8) Once the two configurations described in point 4) and 7) have been created, you can rapidly pass from one to the other by executing the “Label management” command and selecting the desired configuration from the list at the top on the left.

5. Calculation and Dimensioning This chapter describes:  the DOC calculation potential;  results of the calculation;  verification of existing plants. After reading this chapter, the user will be able to:  understand what is calculated by the program;  understand how the calculations are done;  solve most of incorrect situations highlighted by the program;  read the calculation results;  customize the program choices.

Page 46 of 170

5.1.

Calculation and Dimensioning When the single-line diagram drawing is completed and the data of the Single Objects have been defined, it is possible to calculate the single-line diagram. DOC is fitted with a powerful calculation engine able to automatically carry out long and complex operations which would take a long time to carry out manually or using other less powerful software. In particular the DOC calculation engine is able to:  Verify correctness of the single-line diagram design  Calculate the load currents at all points of the diagram  Calculate the voltage drops  Balance single-phase - two-phase loads over the three phases  Calculate the power consumed by the supply and the power factor  Dimension the cables according to the calculated load currents and/or the voltage drops  Repeat steps 2 and 3 until all the cables have been correctly dimensioned  Calculate the maximum and minimum short-circuit currents at all points of the singleline diagram  Select the protection devices according to the load currents, short-circuit currents, protection of cables and people, and if required, coordinate the protection devices (discrimination and/or back-up). The calculation is done using the “Calculate” button of the “Work flow” toolbar. All the calculation parameters are preset so as to satisfy the needs which are found in the most common plants, therefore starting the calculation is immediate and does not require any further decisions by the user.

Advanced Calculation Settings Some parameters used in the calculation procedure can be modified by the user. This operation is generally not indispensable because the parameters are preset so as to satisfy the most common needs. Therefore, to view and modify these parameters it is necessary to use the “Options…” command in the “Tools” menu, and to select the “Show calculation settings before dimensioning” box on the “Calculation options” page, Modification of the advanced calculation options is only recommended for expert users and those with special requirements. In fact, they regard:  Definition of the instants at which to calculate the short-circuit currents;  Tolerance over the power supply voltage;  Reference temperature of the cables for calculation of the maximum short-circuit currents;  Type of over-excitation of the generators present in the diagram;  Manual exclusion of the motor contributions in calculating the short-circuit currents.

DOC – User Manual - Page 47

Minimum and Maximum short-circuit currents DOC calculates the Minimum and Maximum short-circuit currents it all points of the network. Their difference is explained in the IEC 60909-0 Standard in chapters 2.4 and 2.5 (the differences are also given in DOC during printing in the “Short-circuit Calculation Hypotheses”; 9.2.3). It is important to underline that, with regard to the end-of-line fault currents, DOC calculates:  The Minimum fault current in the cable, used for protection against indirect contacts (Cf. Chapter 6.1).  The Maximum fault current in the switchboard on the load side of this line, used for selection of the Breaking Capacity of the protection devices installed in the switchboard. Two different short-circuit values are therefore available at the end of the line, defined as follows: Maximum short-circuit currents 

To calculate the maximum short-circuit currents, the voltage factor cmax (equal to 1.05 or 1.1);  The motors are included if their contribution is higher than 5% of the maximum shortcircuit current calculated without this contribution;  The resistances of the lines (overhead and in cables) are taken at a temperature of 20°C. Minimum short-circuit currents   

To calculate the minimum short-circuit currents, the voltage factor cmin, equal to 0.95, is applied; The contribution of motors is excluded; The resistances of the lines (overhead and in cables) are taken at a temperature of 80°C.

The values of the cable resistance at 20°C and at 80°C can be printed by enabling the “Table of LV cables” of the project documentation (Cf. Chapter 9.2.4.).

During calculation, a window is visible which shows the state of progress of the process.

Calculation Window During calculation, messages may appear, when significant or abnormal situations occur. The meaning of the main messages is explained in chapter 5.2. According to what is found by DOC, the Single Objects may change color in conformity with the profile of the colors (Cf. chapter Error! Reference source not found..) on completion of he calculation. It may also occur that in some situations DOC is not able to select some switching and protection devices. The main cases which may occur are explained in chapter 5.3. The results available on completion of calculation and the methods for displaying these are described in chapter 4.7. The main actions which can be taken on completion of the calculation to verify the results and, where necessary, to modify the program selections are described in chapter 5.5.

DOC – User Manual - Page 49

5.2.

Error Messages This chapter explains the most important and frequent error messages that can appear during calculation. The error messages which could appear during calculation are of two types:  Blocking messages: warn of a critical and incorrect situation which must be corrected before being able to proceed with the calculation.  Warning messages: draw the user‟s attention to an anomalous or potentially incorrect situation but do not block the calculation process. Blocking messages  Phases – Distribution system not consistent in the highlighted Objects DOC verifies the congruence of the single-line diagram (for example: a single-phase cable cannot supply a three-phase load). Solutions: verify the phase and distribution system properties in the Single Objects indicated. In the case of any discrepancies, cancel and draw new the Single Objects or modify the Phase and Distribution system properties after having carried out a Multiple selection (Cf. Chapter 4.6) of the Single Objects involved.  Single-line diagram incorrect: it is necessary to add a power source between supply and loads. Verify the Highlighted Objects DOC needs at least one Single Object with impedance not nil (for example, a cable or a busway) to be present between supply and loads. Solution: verify that there is at least a cable or busway between the supply and the loads.  Single-line diagram incorrect: it is necessary to add a power source between two supplies. Verify the Highlighted Objects DOC needs at least one Single Object with not nil impedance (for example, a cable or a busway) to be present between two supplies which work in parallel. Solution: verify that there is at least a cable or busway between the two power supplies.  Single-line diagram incorrect: some objects are short-circuited! Verify the Highlighted Objects. DOC verifies that there are no branches with nil impedance in parallel with Single Objects or branches of the plant: the latter would, in fact, not be passed through by current and this is indication of an error in the single-line diagram drawing. Solution: verify the connections between the two short-circuited Single Objects.  Single-line diagram incorrect: connections missing. Verify the Highlighted Objects A part of the single-line diagram is not connected to the supply. Solution: connect the Highlighted Single Objects to the supply.  Single-line diagram incorrect: links not connected. Verify the Highlighted Objects A link has not been connected to the relative arrival. Solution: verify the link indicated and connect it to another link; should the link be superfluous, cancel it.

Page 50 of 170

Warning messages  Voltage drop higher than the limit set for the highlighted Objects DOC verifies that there is a voltage drop percentage no higher than 4% (or than the value entered by the user) on each load and signals the loads for which the threshold has been exceeded. Solution: verify the sizes of cables on the supply side of the load involved.  The transformer highlighted is not dimensioned correctly: increase the size! DOC verifies that the transformers are able to supply the power required by the plant. The message generally appears when the transformers have been locked with a padlock, otherwise DOC would be able to select another power transformer suitable for the load required automatically. Solution: Increase the size of the transformer, verify that the power of the loads and the demand coefficients have been entered correctly.  These objects are not protected against overload \ short-circuit \ indirect contacts DOC verifies that all the cables and switching devices are protected against faults (the warning can be disabled in the window which communicates the warning). Solution: It is not always necessary to take measures (for example, in the case of missing protection against overload in the emergency configurations): the user can decide, under their own responsibility, to omit the protections when the Standards and/or the characteristics of the plant allow this. If necessary, add a protection device on the supply side of the unprotected object.  Attention: some supplies consume power instead of supplying it DOC verifies if the flow of power goes from the supply to the loads. In the case of several power supplies in parallel (generator and power supply) a generator may satisfy the power required by the plant and also supply energy to the power supply. Solutions: if you do not want the generator to supply energy to the power supply, verify the size of the generator, the power of the loads and the demand coefficients. If it is normal for the generator to supply power to the network in the plant, the message is confirmation of this behavior.  Attention: some supplies have lower rated power than the one required by the plant DOC verifies that the generators and the UPS are able to supply the power required by the plant, comparing their rating plate data with the requirements of the loads (the supply is considered to be a generator with infinite power). Solution: in this order, verify the rating plate data of generators and UPS, the demand coefficients and the power consumed by the loads.  In the highlighted cables the following dimensioning criteria are not verified: - The carrying capacity is insufficient - The voltage drop exceeds the limit set DOC verifies that the locked cables (Cf. Chapter 5.5) satisfy the carrying capacity and voltage drop criteria. Solutions: verify the cable data (length, insulation, method of installation) and the load data; or trip unit the cable and let DOC re-calculate the section.

Failed Selection of Single Objects Sometimes DOC is not able to find a valid product, or shows the products locked by the user with the padlock as invalid. The most frequent cause of failed selection or verification of a product are listed below and can guide the user to modify the selection criteria appropriately. 

If the Single Object is locked with the padlock, unlock it and restart the calculation.



Verify that the appropriate protections against indirect contacts with the power sources by means of residual current devices are present, when the distribution system is TT. It may be impossible to ensure protection against indirect contacts with other protection functions.



In the case where the fault current is high (over 15kA) and the section of cable to be protected against short-circuit is less than 4 mm2, try to restart the calculation after having selected a cable with a larger section and having locked it with the padlock.



Verify that you are do not find yourself in one of the cases specified below, for which no suitable products exist: o 1P, 1P+N and 2P products in circuits with current higher than 125A (the 1P, 1P+N and 2P devices are of modular type and have a maximum rated current of 125A. It is necessary to select 3P, 3P+N or 4P devices. o Residual current protection with rated current higher than 2000A (the maximum size of an RCQ external toroid is 2000A). o Fuses with rated current higher than 630A (the maximum rated current of the fuses managed by DOC is 630A). o Fuses with breaking capacity higher than 100kA (the fuses have a breaking capacity of 100kA. If DOC has calculated higher short-circuit currents, verify the supply data, or select a circuit-breaker instead of a fuse). o Circuit-breakers with breaking capacity higher than 200kA (The circuit-breakers have a breaking capacity maximum of 200kA. If DOC has calculated higher short-circuit currents, verify the supply data). o Molded-case circuit-breakers with rated current higher than 160A to protect residual current circuit-breakers (it is not possible to carry out protection of residual current circuit-breakers with molded-case type circuit-breakers with rated current higher than 160A). o Molded-case circuit-breakers with current lower than or equal to 160A to protect residual current circuit-breakers with short-circuit current higher than 6kA (molded-case circuit-breakers with rated current up to 160A can only protect residual current circuit-breakers up to 6kA). o Miniature circuit-breakers in circuits with current higher than >125A or breaking capacity >25kA. In this case, remove the limit on the type of product and allow selection of a molded-case type of circuit-breaker.

Page 52 of 170



If a fuse, or a switch-fuse, protects a cable, verify that the relation between Iz and Ib is at least equal to 1.2 (Cf. Chapter 6.1.1: a cable with Iz of 30A can only be protected by a fuse up to 0.9 x 30A = 27A.



If a circuit-breaker protects a cable, verify that between Ib and Iz there is space to be able to select a size of product. For example,: if Ib is 26A and Iz is 30A it is not possible to select a miniature circuit-breaker to protect these since the closest sizes are 25A, lower than Ib, and 32A, higher than Iz.



Verify that there are not too many objects protected by the same protection device (the window to display \ modify the list of the protections is described in Annex B).



For the circuit-breaker, verify that there are not too many simultaneous discrimination, back-up and cable protection restrictions. In this case, slacken one or more of the restrictions.

Help for Failed Selection of Single Objects In the case where it is not possible to achieve selection of a product using the suggestions given above, you can the send the project file and a description of the anomaly to assistance service which is at your disposal.

Calculation and Dimensioning Results Calculation results DOC calculates the following, both in low and in medium voltage:  Maximum short-circuit currents at all points of the single-line diagram.  Minimum short-circuit currents at the end of the line.  Phase and of neutral currents (in unbalanced networks) at all points of the single-line diagram.  Power factor on each line and at each busbar.  Active and reactive power required at the supply. Dimensioning results The program is able to select the following, both in low and in medium voltage:  The minimum sections of the cables which satisfy the following criteria: o thermal according to the Standard selected o voltage drop on the single line less than 4% (modifiable by the user)  The most economical protection apparatus (circuit-breakers, fuses) on the list of technically correct ABB products.  The most economical switching apparatus (disconnectors, contactors) on the list of technically correct ABB products. Further results Other results coming from a calculation:  Balancing unbalanced networks. The program applies an algorithm to “move” the single-phase and two-phase loads from one phase to the other, so that the consumption of current on the supply side is as balanced as possible.  Dimensioning for the rated current of a transformer or generator. The Single Objects placed on the load side of a transformer or generator will be dimensioned according to the rated current of the secondary winding of the transformer or according to the rated power of the generator, instead of to the current required by the plant. This option is useful for those who possess machines dimensioned taking future enlargements of the plants into consideration. Cables and switching and protection devices will not have to be changed, with obvious savings in execution times and costs.

5.5.

Changing the Dimensioning Results. This chapter will explain how to modify the selections made automatically by the program.

Locking and Unlocking Single Objects During the stage of modifying the program selections after dimensioning, the most important commands, are those which allow a Single Object to be Locked or Unlocked. The “Lock objects” command modifies the calculation settings, so that at the next dimensioning, the locked Single Object is only checked and not modified by DOC. The locked Single Objects behave as follows: Object Cable Protection device Switching device Transformer Load

Effect of the lock The section is not re-calculated. The product is not changed with a more economical one. The product is not changed with a more economical one. The size is not re-calculated according to the loads. The single-phase loads are not connected to a different phase in order to minimize the unbalance.

The “Unlock objects” command resets the calculation settings, so that at the next dimensioning, the unlocked Single Object is selected by DOC. The unlocked Single Objects behave as follows: Object Cable Protection device Switching device Transformer Load

DOC – User Manual - Page 55

Effect of the lock DOC re-calculates the section, optimizing it according to the voltage drop and the carrying capacity The most economical product among those technically suitable is proposed. The most economical product among those technically suitable is proposed. The size is re-calculated according to the loads. If this is single-phase, it can be connected to a different phase to minimize the unbalance.

Changing a product The automatic selections made by DOC cannot take into account every single requirement of all the program users! To change a product proposed by DOC, simply:  Enter the Single Object Properties window.  Click over the “Select >>>” button  Navigate the tree to find the desired product.  Lock the desired product with the padlock. Entering the selection window, the list of products displayed considers the technical selection filters of the product (for example, circuit-breakers with breaking capacity lower than the short-circuit current will not be shown). If the desired product is not on the list, remove the technical filters by selecting the “Free selection” option at the top on the left.

“Select >>” button in a circuit-breaker window At the next calculation, DOC will verify the locked product instead of selecting a new product. Changing cable sizes DOC selects the cable sections according to the Standard, to the carrying capacity of the cable and to the voltage drop. Changing the cable sections, for example, to verify a cable already installed, is possible by entering the cable Properties window. In this window, select the most suitable sections for your situation and lock the selection with the padlock. Modifying the size of a cable changes the impedance of the cable itself and therefore the voltage and short-circuit values on the load side of the cable. New values of the short-circuit currents could invalidate the selections relative to the protection devices already selected: it is therefore necessary to re-calculate the whole single-line diagram !

6. Verification and Protections This chapter describes:  verifications of the overload, short-circuit, indirect contacts and discrimination from a theoretical viewpoint;  the verifications carried out by the program. After reading this chapter, the user will be able to:  understand the overload, short-circuit, indirect contacts and discrimination verifications;  use the curves module to carry out overload, short-circuit, indirect contacts and discrimination verifications.

DOC – User Manual - Page 57

6.1.

Verifications and Protections This chapter describes how to verify cable protection and the discrimination criteria by means of the module dedicated to drawing the curves.

6.1.1.

Description of the Protections DOC verifies the protections against the following in real time:  Overload (hereinafter OL).  Short-circuit (hereinafter SC).  Indirect contacts in TT systems (hereinafter NDT-TT).  Indirect contacts in TN systems (hereinafter NDT-TN). The protection criteria are defined in the standard IEC 60364-4-43: 

Overload (IEC 60364-4-43Standard Chapter 433): The set current of the protection device (In) must be between the service current (Ib) and the carrying capacity of the power source (Iz).

Ib  In  Iz -

The threshold of guaranteed tripping of the protection device must be less than 1.45 times the carrying capacity of the power source.

I 2  1.45  Iz where:

Ib = Service current. Iz = Carrying capacity in permanent regime of the power source. In = Current set of the protection device (for non-adjustable protection devices, this coincides with the rated current).

I2 = Current which ensures effective operation of the protection device within the prearranged time under defined conditions.

Current for Guaranteed Circuit-breaker Tripping and Fuse intervention For construction characteristics, the I2 current for guaranteed tripping is: -

Always less than or equal to 1.45  In for circuit-breakers

Equal to 1.6  In for fuses. It follows that: A circuit-breaker is able to protect a cable against overload over the whole of its carrying capacity, making the verification superfluous I 2  1.45  Iz In a fuse, the most strict condition is verification on I2. Replacing I2 with the value

1.6  In , you obtain:

1.6  In  1.45  Iz From which it follows that:

In  0.906  Iz In other words, protection of a cable against overload by means of a fuse does not allow use of this cable up to its carrying capacity, but only up to about the 90% of its carrying capacity.

Page 58 of 170



Short-circuit (IEC 60364-4-43 Standard Chapter 434): o The specific energy let-through by the protection device is lower than the specific energy supported by the cable for all the current values from Ib to the maximum short-circuit current. With DOC, the verification is carried out graphically by comparing the curve of the specific energy let through by the circuit-breaker (I2t) and the curve of the maximum energy which can be supported by the cable (K2S2) and verifying that there are no intersections in the range of currents defined by the Standard.

Diagram of energy: comparison of the curves of a circuit-breaker (blue) with a completely protected cable (black) and a partially protected cable (red) 

Indirect contacts in TT systems (IEC 60364-4-43 Standard Chapter 413): o The contact voltage is less than 50 [V] i.e.:

Ra  Ia  50 where: RA [Ω] = Sum of the resistances of the ground plate and protection conductors of the exposed conductive parts. IA [A] = Current which causes automatic operation of the protection device (if the protection device is of the residual current type, IA is the rated Idn residual current).

DOC – User Manual - Page 59

Modifying the RA Value As described in the previous paragraph, RA is given by the sum of two resistances: the ground plate and the protection conductors of the exposed conductive parts.  Ground plate: its value is defined in the “General plant properties” (cf. Chapter 3.2). If necessary, it is possible to set a different value of the ground plate for each single feeder in the “Protected Objects” window of the protection device (“LV circuitbreaker”, “LV Fuse”, “Residual current circuit-breaker”) placed on the supply side of the feeder itself.  Protection conductors of the exposed conductive parts: the value of the resistance of the conductors is calculated by the program according to the type of cable and its section. The values of the conductor resistances can be o Consulted in the “LV cable” properties (Cf. Annex B); o Printed in the “Table of LV cables” 9.2.4). 

Indirect contacts in TN systems (IEC 60364-4-43 Standard Chapter 413):: o The trip threshold of the protection device must be lower than the fault current at the end of the Phase – Ground line, i.e.:

Zs  Ia  Uo where: ZS [Ω] = Impedance of the fault ring which includes the source, the live conductor as far as the fault point and the protection conductor between the fault point and the source (in DOC, this type of fault is called “L-PE”, i.e. between phase and protection conductor).

IA [A] = Current which causes automatic operation of the protection device within the time defined in the following table (if the protection device is of residual current type, IA is the rated residual current Idn). Uo [V] 120 230 400 >400

Trip time [s] 0.8 0.4 0.2 0.1

U0 [V] = Effective value of the rated voltage between phase and ground. DOC calculates the value Uo Zs , indicated as “Icc L-PE” (short-circuit fault current between Phase and Protection conductor). The verification carried out is therefore:

Im  IccL  PE where: IM [A] = is the current which causes protection device tripping within the scheduled tripping time.



Indirect contacts in IT systems (IEC 60364-4-43 Standard Chapter 413): o In IT systems the live part of the network is electrically insulated from the exposed conductive parts, therefore the circuit of any possible ground fault can only be re-closed in capacitive couplings between live conductors and exposed conductive parts or groundings (as in the diagram below). The value of these capacitive couplings cannot easily be calculated, making it impossible to give a value to the impedance of the fault ring and therefore to the current which passes through it.

Circuit of a ground fault in a IT system Not knowing the value of the first ground fault, DOC is not able to verify the protection against indirect contacts. Remember that, in any case, the above-mentioned Standard foresees the use of an insulation control device to indicate appearance of an initial fault between a live part of the network and exposed conductive parts or ground. The same Standard does not impose protection against indirect contacts in IT systems by means of automatic interruption of the power supply. The parameters used for verification of protection against indirect contacts can be modified in the “General plant properties” window (Cf. Chapter 3.2).

Further Information about Protection against Indirect Contacts For further information, we recommend consulting the “QT3 - Distribution systems and protection against indirect contacts and ground faults” guide for more details on the subject.

DOC automatically assigns cable protection to the most suitable device on the supply side. However, it is possible to modify the program selections by pressing the “Advanced Options >>>” or “Protected Objects” buttons which are always present in the windows dedicated to each protection device. Removal of the protection restrictions of switching devices or power sources might leave these objects unprotected in the case of a fault. We recommend using this option very carefully.

Verifying Protections

Curves Module Manual This Chapter only contains basic indications about using the curves module. For a detailed explanation on how to set the trip units and on the functionalities of the application, please consult the “Curves Manual” user guide in the DOC “Help” menu. Verification of the protections is carried out with the curves module, which is enabled by clicking over the icon shown on the left and which is located in the “Work flow” tools toolbar. Once the command is given, DOC shows a new work environment where it is possible to work on the curves of the devices present in the diagram and on all the settings available.

Main curves module window. The “Relations”, i.e. the list of protections verified by DOC, are shown in the lower part of the screen.

DOC – User Manual - Page 63

The “Relations” window is divided into four columns:  Object on the supply side (protection device, a circuit-breaker or a fuse).  Object on the load side (object protected, typically a cable).  Verification calculation carried out by DOC (the calculation is done in real time as soon as a curve is modified and in conformity with the criteria expressed previously).  Present state of the verification. If a protection relation is satisfied, the text which describes it is black and the state is “OK”. If a protection relation fails, the text which describes it is red and the state is “Failed”. You can print the results of all the verifications made by DOC in the “Report of protections” (Cf. Chapter 9.2.9).

Examples of satisfactory and failed verifications

Select the failed verification by ticking its box; The curves module will show the diagram of the specific let-through energy (I-I2t); The protection device and the cable the verification refers to will be shown; There may be circuit-breakers of large size and fitted with a microprocessor trip unit: in this case enable functions “S” and “I” of the microprocessor trip unit and modify the setting until the circuit-breaker curve is completely under the cable curve; The color of the message will change in real time from red to black, when the protection relation has been verified.

Verification of protection against indirect contacts

DOC – User Manual - Page 67

Select the failed verification by ticking its box; The curves module will show the Phase-ground fault current – Time (I-t LPE) diagram Select the circuit-breaker curve by clicking over it; Click over the “min Ik” icon: the command makes a vertical straight line appear in the diagram which represents the fault current at the end of the line. A positive verification is obtained when the magnetic threshold of the circuit-breaker is on the left of the fault current at the end of the line; Lower the magnetic threshold of the thermomagnetic trip units, or enable thresholds “S” or “I” of the microprocessor trip units and use sufficiently low setting values; The color of the message will change in real time from red to black, when the protection relation has been verified.

Verification of discrimination

Verification of short-circuit Discrimination is achieved when both the following conditions are satisfied:  The circuit-breakers have been selected by assigning them the discrimination restriction in the single-line diagram (Cf. Annex B, “LV circuit-breaker” chapter).  The curve of the circuit-breaker on the supply side, in the Time-Current diagram, does not intersect the one of the circuit-breaker on the load side. When the program notifies failed discrimination verification, it is advisable to proceed as described below:  Select the failed verification by ticking its box;  The curves module will show the Time-Current diagram (I-t)  Double click over the circuit-breaker on the supply side, by accessing the mask for setting its trip unit.  If the trip unit is of thermomagnetic type (“Circuit-breaker with thermomagnetic trip unit”), raise threshold “I” up to the maximum value allowed.  If the trip unit is of microprocessor type (“Circuit-breaker with microprocessor trip unit”), disable function “I”; o Once function “I” has been disabled, it is advisable to enable function “S” (protection against delayed short-circuit); o Raise threshold “S” both in time and in current until discrimination is obtained.  The color of the message will change in real time from red to black, when the protection has been verified.

Page 68 of 170

The hatched area appears in the diagram when a discrimination verification has been selected. This area represents the maximum discrimination value which can be achieved by the pair of circuit-breakers. The maximum discrimination value is defined as:  The magnetic setting of the circuit-breaker on the supply side minus the tolerance, if: o The circuit-breaker on the supply side is fitted with a microprocessor trip unit and function “I” is enabled; o The circuit-breaker is fitted with a thermomagnetic trip unit and the setting of the magnetic threshold “I” is lower than the maximum value allowed.  The value of discrimination published in the ABB “Coordination Tables” if: o The circuit-breaker on the supply side is fitted with a microprocessor trip unit and function “I” is disabled; o The circuit-breaker is fitted with a thermomagnetic trip unit and the setting of the magnetic threshold “I” is equal to the maximum value allowed.

Further Information about Discrimination Verification. The “QT1 - Discrimination in low voltage with ABB circuit-breakers” guide is available in the “Help” menu. It is advisable to consult this for in-depth information on the subject.

Discrimination Studies between MV Apparatus and LV Apparatus The “QT2 - MV/LV Substations: theory and short-circuit calculation examples” guide is available in the “Help” menu. It is advisable to consult this for in-depth information on the subject.

Impossibility of Verifying all the Relations. It may not be possible to satisfy all the protection relations simultaneously, since a setting made to satisfy one may not allow satisfaction of others. This can occur, for example, if both protection against indirect contacts and discrimination with circuit-breakers on the load side must be guaranteed using the same protection device: the former requires a low magnetic setting, whereas the latter requires high values or disablement of function “I”. It is advisable to:  Replace the thermomagnetic trip units with microprocessor ones, provided with several possibilities during the setting stage.  Use trip units fitted with function “G”, which allows you to have high magnetic settings for verification of discrimination and low magnetic settings for protection against indirect contacts.

Verification of Back-up DOC is able to select circuit-breakers coordinated by means of back-up. This relationship does not require any further verification: back-up is a function of the construction characteristics of the circuit-breakers and does not depend on the trip unit settings. The back-up value is declared by the Manufacturer in the ““Coordination Tables”.
