REF542plus – Hardware, Analog input modules
REF542plus can have a maximum of 8 analogue input channels. These inputs are divided into three measurement groups: •Measurement Group 1: channel 1, channel 2, channel 3 •Measurement Group 2: channel 4, channel 5, channel 6 •Measurement Group 3: channel 7, channel 8 Group 1 and group 2 have to be homogeneous, that means they can measure 3 currents or 3 voltages. For example, measurement of 1 current and 2 voltages is not allowed. Group 3 can get any type of signals: 2 currents, 2 voltages, 1 current and 1 voltage, etc. The input CT 0.2A is commonly used with a toroidal transformer for sensitive earth fault current measurement. CT means input for current transformer (CT2 is the 0.2A input). The instrument transformer can have ratio /1 or /5 . The ratio and the nominal current (e.g. 100/5) are selected via software in the configuration tool. The input module is the same; a different pin on the connector is wired depending on the ratio /1 or /5. VT means input for voltage transformer. Both Phase-to-ground or phase-to-phase VT can be used. SI means sensor input. The rogowsky coil is used for current sensing. The correct ratio of the rogowsky coil is selected by the configuration tool. The resistive divider is used for voltage sensing. The ratio is selected by the configuration tool. The input is the same both for voltage and current sensing, the selection is done via the configuration tool. So, it is possible to use 6 rogowsky coils, or 6 voltage dividers, or 3 rogowsky coils and 3 voltage dividers.

PFC with Resonance Protection
The problem – Network parameters changes may cause resonance behaviour at capacitor or load switching
– Resonance frequencies originates current and voltage distorsion with increase of power losses
REF542plus resonance protection monitors continuosly the network total harmonic distorsion (THD) – Resonance protection detects harmonics caused by PFC operation (switching resonance).
– Resonance protection clears the oscillation by de-energizing the capacitor banks (PFC coordination) Case 1 Voltage waveform at BUS9A 1.5

REF542plus Applications
REF542plus – Integration in SCADA system
Four different communication protocols are available.
REF542plus can thus be easily integrated in any SCADA systems.
Distributed intelligence architectures result in a high degree of plant automation to:
Manage different loads and plant configurations
Change and modify the power network distribution
Acquire Advanced
measurements and status information
functions are also possible:
Primary parts status verification
Circuit breaker electrical and mechanical life analysis
Preventive maintenance plans

REF542plus Customer Values
Flexibility and advanced functions:
Very complex automation sequences possible.
Flexibility also after commissioning: software changes, no new wiring.
Wealth of information in case of primary faults (fault recorder, event time, etc).
Everything in one box, which is always the same:
Trafo feeder, motor feeder, overhead lines feeder, etc.: the box is always the same.
One kind only of spare part.
One human machine interface only to learn.
