ELECTRICAL AND C&I IDENTIFICATION
Two types of code are necessary for identification of electrical and C&I and functions, as follows: •
Process related code: Identification of electrical and C&I equipment and functions, for example, power transmission, switchgear, transformers, unit protection, functional group control.
•
Point of installation code: For the unique addressing of the points of installation of electrical and C&I components, for example, in control consoles, panels, cubicles and cabinets. In addition to these two types of identification for which the KKS establishes rules, the following codes are necessary :
•
Connection Code When the KKS rules be inadequate it can be used the DIN 40719 Part 2 for connections to identification of installation units, installation spaces and components. The DIN mask is as follow: Installation Unit Code
Installation space Code
N A A A N N A N1 … … ... N8 Max 8 data characters This code should start with an alpha character. •
Cable Code For the identification of cables and wires.
•
Cable Conduit Code For the identification of cable conduits.

Starts anew when the preceding classifying code element changes;
•
Numbering may be consecutive or grouping;
•
Numbering need to be continuous;
•
Numbering convections, once established, may not be altered;
•
The possibility of later addition to the system should be considered.

Level 2 (Installation space code) There are possible methods of installation space identification: •
No subdivision into installation spaces, e.g. 10 kV cubicles. In this case don’t use the Level 2.
•
Subdivision into installation spaces. This correspond to the layout that it was assumed. In this case, D1D2 gives the vertical subdivision (rows) and D3D4 D5 gives the horizontal subdivision (columns).
The rules that must be applied are: •
Direction and sequence of numbered – The left to the right and the Top to the bottom.
•
Additional data may be necessary and in this case we can use coordinate grids to provide unique identification.
In case of miniature hardware systems we can fix subdivision with coordinate grids. The top left hand corner is used to give the reference of the component.
If it is necessary to create additional fittings referenced to the grid, numbering starts from the coordinate system origin of the prescribed grid, proceeding in descending order from 1000, against the direction of numbering.
N.º 1.2.060-PG-005-RL-2010
REV.: 1
FL.: 20 / 74
If it is necessary to create additional fittings not referenced to the grid, installation zones are identified with first letter of breakdown Level 2.
Subdivision without fixed coordinates. The rules described above are applied. This can be identified by the near row letter or by a sequential numbering.
D3D4 D5 Installation space code (Horizontal subdivision-columns of installation spaces in installation units) D6
Additional code for subdivision of Level 2. Sometimes, in electrical cabinets it is necessary to identify components in depth. In this case we can use the letter E with combination with numbering and letters.
In C&I, the rules for identifying cabinets are the same as switchboards. For control stations and control room desks we can use the following procedure: • Create a horizontal and vertical grid starting at AA000 (left hand corner). • The area cover different orientations, e.g. from vertical to angled as with the transition from vertical panel to inclined board.

5.4 Cable Identification The cable identification includes a classifying and a numbered code element. The processrelated or point of installation code is used in part or in full for a classifying element, with the code of the two cable ends which come first in the alphabet generally being adopted for the classifying element of the cable code. The numbering element of the cable nº consists of 4 or 3 numeric and 1 alphabetic data character. The mask is as follows: Classifying Element

In general the cables are identified with the code of the cable destination which is first in alphabetic order. The numbering element of the cable no comprises four numeric data characters or three numeric and one alfa data character. The numeric data characters may be used four grouping within the cable no; when it is necessary
the alfa data character may serve to
distinguish parallel cables or application areas for example. Grouping of the cable no is recommended in order to keep agreements on the allocation of cable nos during planning to a minimum and to prevent multiple allocation of cable nos, e.g. group by technical application areas, suppliers, etc. The first digit of the four numeric data characters serves to identify the application area, the three other numeric data characters to number cables within that area.

5.5 Cable Conduit Identification To identify the cable conduit we will go use the EDP specification based on the KKS installation code with the following mask: Plant Unit
Installation unit code
Conduit type code

(2)
B B
C0 C1 C2 C3 C4 C5 D1 D2 D3 D4 D5 D6
Level 0 (Plant Unit number) Examples : 1 = Plant Unit 1, 2 = Plant Unit 2, 3 = Plant Unit 3 A = Common to unit 1 and 2 B = Common to unit 3 and 4 9 = Common to the Power Plant
C0
Level 0
(Special number to identify System code with the same function –
reserved field – take the value 0) Example: 10 C1 C2 C3
= unit 1 equipment
Level 1 (Installation unit Code) Example: UMA= turbine housing
C4 C5
Level 1 subdivision Example: UMA01 = zone 1 of turbine housing
D1 D2
Level 2 (Conduit type) We have the following conduits type: EH = Horizontal conduit – conduit in horizontal or non-vertical position EV = Vertical Conduit – conduit in vertical position CI = Individual conduit – conduit for one consumer derived of one general conduit. It can be in a pipe, cable support or clamp iron. CE = Exterior conduit – conduit inside a concrete channel CV = Burried conduit – conduit in trench cable T* = Tunnel conduit – conduit inside concrete tunnel. The * can be the letters A, B, C, … and is used to do the subdivision of the tunnel in sections. TE = crossing road – when the conduit cross one road. Example:
N.º 1.2.060-PG-005-RL-2010
REV.: 1
FL.: 27 / 74
UBZ02TC = tunnel no 2, section C D3 D4 D5
Level 2 Subdivision (Shelf) It is a numeric field and have the following rules: •
D3 - define the level/position of the shelf and increase from top to bottom (0 till 9);
•
D4 – define the channel. The electrical philosophy concept is made in dual channel (A, B). This means that any dual equipment must have assigned one dual conduit cable. In this way we increase the availability of the plant because half of the plant is put out of service in case of a cable firing. For example, each feedpump motor must be supplied by different conduit cable. Then we will go use odd numbers for channel A and even numbers for channel B. It assume the numbers : o
A = 1,3,5,7 and 9
o
B = 2, 4, 6 and 8
When the equipment is not dual, for example, diesel engine, we will go use for the cable the conduit that have less cables. •
D5 – sequential number of the main conduit or derivation. Assume the values 0 till 9.
•
The number remains unchanged when there is path changing except when occurs changing on the dimension, cross road or mounting type.
Example: If the conduit UBA01EH110/B changes to vertical position the reference changes to UBA01EV110/B. The reference gives the exactly path that conduit do. •
There will be different numbers according to the voltage levels, e.g. power cables for medium and low voltage, cables for C&I and other cables (telephone lines, intercom, etc).
Example: UBZ02TC006 = tunnel no 2, section C, shelf no 6 D6
This character is to identify the conduit design voltage level. It takes the following letters:
N.º 1.2.060-PG-005-RL-2010
•
A = Voltage level ≤ 60 V
•
B = Voltage level > 60 V
REV.: 1
FL.: 28 / 74
•
C = Voltage level ≤ 1 kV AC (LV voltage including illumination)
•
D = Voltage level > 1 kV AC
•
E = Voltage level ≤ 1 kV AC (Batteries, rectifiers, emergency pumps)
•
F = Telecommunication cables (telephones, intercom, etc)
When one conduit serves more then one voltage levels it must indicate all levels. Examples: UMA01EH110/B UMA01EH210/B/E

B
Level 0 (Plant Unit number) Examples : 1 = Plant Unit 1, 2 = Plant Unit 2, 3 = Plant Unit 3 A = Common to unit 1 and 2 B = Common to unit 3 and 4 9= Common to the Power Plant
C0
Level 0 (Special number to identify System code with the same function – reserved field- now take 0)
C1 C2 C3
Level 1 (Structure code) - See the Level 1 KKS codes (Attached I). Examples: UBA = Electrical Building UBB = Building for general electrical services UHA = Boiler House UMA = Steam turbine building URA = Cooling tower UST = workshop building UZT = Outside area UYE = Gate house
C4 C5
Level 1 (Sub-system). Examples: Variant 1 : each structure is considered individually. This means that the numbers don’t correspond to the same level in all structures. UHA07 = Boiler house level 7 (+17.60 m in the example) UMA03 = Steam turbine level 3 (+3.00 m in the example)

Variant 2 : each structure is considered global and there is the floor numbering. The lower level can start with the number 02 to introduce after during the planning the 01 for pump pits. The floors, platforms receive even numbers and the intermediate floors and platforms receive the odd numbers. UHA14 = Boiler house level 14 (+17.60 m in the example) UMA06 = Steam turbine level 6 (+3.00 m in the example)

Variant 3 : each structure is considered global and the objective is identifying floors at comparable elevations with the same floors numbers. The numbering start with 02 for the lowermost floor of the power station. Further the floors number are determined by the ground floors at station grade level, the control room, burner levels, etc. The structure having the smallest spacing between levels governs the sequence of numbering. UHA24 = Boiler house level 24 (+17.60 m in the example) UMA12 = Steam turbine level 6 (+3.00 m in the example)
Variant 4 : each structure is considered global and the correlation between floor numbers and ranges of elevations are agree before start the identification. UHA27 = Boiler house level 27 (+17.60 m in the example) UMA13 = Steam turbine level 13 (+3.00 m in the example)

EXAMPLES IN POWER TRANSMISSION For power transmission is recommended to follow the rules: •
Numbering in groups of ten
•
Starting from generator neutral
•
90s numbering for generator leads ventilation system
Example 1 - Single Line diagram Use the following rules for transformers: •
BA for generator transformers, BC for start-up transformers, direction of energy flow.
•
Cooling for transformers under group B, water cooling under P, Fire fighting under S, stationary fire protection under SG.
•
The windings of transformers are identified in the equipment unit code with GT for transformer equipment and numbered in D3D4D5 starting from high voltage side.

Example 4 – Windings identification
Example 5 – Auxiliary power supply (switchgear, batteries, battery chargers, inverters) These units are classified, depending on their locations, in the alpha element of breakdown level 1 and numbered in the numeric element as units (cubicles, rows,etc). normally the C1C2C3 of Point of installation Identification are sufficient.
The batteries for equal voltage levels and for the same tasks may be numbered in C1C2C3 of Point of installation Identification. The method of numbering must be agree during the project (C4C5). Example 6 – Emergency generating sets (Diesel) This is classified under BRV group. Because this group is limited we must use the X group that gives more definition. The Cubicle 4 = XKA01GS001+BDC04

Example 7 – Incoming Feeders and Tie Feeders for auxiliary power supply The classification is based on the destination principle, i.e. outgoing, incoming and tie feeders receive the process related code of the recipient. Cubicle 3 of unit1 plant: Process related code = 10BHT30GT001 Point of installation +BBC03 Cubicle 2 of unit 1 plant: Process related code = 10BHT30GT002 Point of installation +BHC02 Note: Transformer code: High Voltage = GT001 Low Voltage = GT002
Example 8 – Cubicles for auxiliary buses The cubicles receive the code of the transformer. Cubicle 2: Process code=+BBT10GT001 Point of installation= BBA02 Cubicle 3: Process code=+BBT10GT001 Point of installation= BBA03
Example 9 –Incoming feeder of a battery system and DC distribution board BHA Cubicle 2: BTL11GU100+BHA02 BUA Cubicle 4: BTL12GU100+BUA04

Example 10 – Incoming/tie feeders of distribution boards
This example demonstrates the problem of process related codes. The BBA switchboard supplies BBE and BCA. Both receive BBA code. Two variants are possible: Variant 1 – Use the C4C5 to discriminate (00 till 99) and GS for switchgear equipment Cubicle 2 of BBE = BBA00GS001+BBE02 Cubicle 1 of BCA = BBA00GS002+BCA01 Disadvantage : Destination not immediately apparent (cubicle not indicated) Variant 2 – Addition of actual cubicle no of destination in C1C2C3. Cubicle 2 of BBE = BBA04+BBE02 Cubicle 1 of BCA = BBA07+BCA01 Disadvantage : Dependence in planning on destination and therefore susceptible to change. Example 11 – Outgoing feeders for loads (one Supply) The feeders receive the KKS process code of the load.

EXAMPLES IN IDENTIFICATION OF C&I EQUIPMENT The C&I equipment is identified in the Function key in main groups C and D. The group D is reserved and can be used if C and D is not sufficient. The identification of C1C2C3 is made with the following principles: •
According to subordinate control and instrumentation task, e.g. instrumentation, open loop control, closed loop control in separate cabinets. o
The majority of C2 coding letters of the main group C is allocated in accordance with this principle.
•
Cabinets containing a variety of equipment (hardwired instrumentation, open loop control, closed loop control together with the power unit in one cabinet). o
•
In this case identification is according to main C&I task on a priority basis.
Structure according to overall C&I task for the process, e.g. functional complexes, unit coordination level, process computer systems, reactor protection, programmable hardware systems. o
Certain groups within the main groups such as CJ for unit coordination level, CK for process computer systems, CL for reactor protection have been specified for this purpose; groups CM-CT are freely available for system combination (e.g. programmable hardware systems) and also main group D if groups CM-CT are insufficient.
The data character C3 is unreserved for almost the entire group C for C&I equipment. Subdivision is possible as required within the terms of stated definition. Example 1 – Available for subdivision Local control station are assigned to CX. We can discriminate the Coal Power Plant control stations as follow: • Coal supply system
CXA
• Ash removal system
CXB
• Cooling Water system
CXC
• Diesel system
CXD
Example 2 – Power Supply, Ventilation and Monitoring cabinets Every cabinet is identified on Level 1 and the Level 2 is used to increase the subdivision. For example: • Power Supply
GW
• Temp measurement circuit
CT
• Cabinet fan
AN
• Heat exchanger
AC

The Level 3 is used for lamps, pushbuttons, limit switches, etc according appendix 1.
Note 1) – Multiple incoming feeders are numbered according 3.2 - example 12, e.g. GW001A and GW001B. For this example we used the CCA03 cabinet. Example 3 – Peripheral equipment for information display and process control Here is included information display and manual control equipment such as video display units, multipoint selection switches, multiple recorders and release pushbuttons which cannot be positively assigned to an equipment unit or a system. We use Level 2 to identify these equipments and the following codes: • Multiple recorders, multipoint
selection
switches
(for
physically
CU
dissimilar variables) • Release pushbuttons
QS
• Peripherals for information display
GK
The following rules apply to multiple recorders/multipoint selection switches: • Recording/measurement of identical physical variables from one system with one device. In this case the indicator/recorder use the KKS level 2 of the measurement and level 3 starts with 9.

• Recording/measurement of dissimilar physical variables from one system with one device. In this case the indicator/recorder use the KKS level 2 of the measurement and level 3 starts with CU.
• Recording/measurement of dissimilar physical variables from different systems with one device. When is used shared control and protection equipment, we use for level 1 the letter Y. The C&I which serves more then one main group is identified under C group, e.g. control room CWA. • Peripheral devices for information display This is the case of the process computer that is identified by CKA and the level 3 by GK.
Example 4 – Junction Boxes On Level 1 the junction box receive the code of the structure and floor on which they are installed. Exceptions are junction boxes for main machine sets/heavy machinery/electrical and C&I cubicles and cabinets which receive the Level 1 of the associated main machine/heavy machinery/cabinet. On Level 2 we use the letter G in C1 and A-F in C2. It is possible to subdivide junction box systems in C2 as appropriate to the plant configuration, e.g. separate junction box systems for analog and binary transmitters. For example we use GA for binary signals connected to the field, GB for binary not connected to the field and GP for lighting (see Attached 1). The numbering is made separately on each floor. A0UMA03GB004 – Junction box for binary signals common to units 1+2 not connected to the field nr 4 on 3rd floor of turbine housing A0UMA02GP001 - Junction box for lightning nr 1 on 2rd floor of turbine housing common to units 1+2 10MAC01GA001 – Junction box for binary signals connected to the field nr 1 of LP turbine 1 of unit 1.

Example 5 – Component identification for circuits connected to electrical junction box To identify the circuits of one junction box we use on Level 2 the letter –E followed by the codes of the individual components in the circuit.
Example 6 – Cable penetration Cable penetrations into and inside structures do not receive separate code. For electrical equipment such as transformers and generators they receive Level 2 equal to GG. Example 7 – Transducer racks, supports and frames This auxiliary equipment is identified like junction boxes on Level 1 and use GZ on Level 2. A0UMA03GZ002 = transducer rack nr 2 on 3rd floor of turbine housing common to units 1+2.
