Description
The fully self-contained KG595E provides precision generator island protection as well as protection against malfunction and human and operational hazards under loss of mains conditions.
The DIN rail mounted digitally controlled unit meets the protection requirements for generators connected to mains supply, such as defined in the G59/2 and similar recommendations.
Less wiring, no extra modules. Operating mode is selected by simple auxiliary contacts on the generator breaker and on the mains breaker. LEDs and open collector outputs indicate operating mode and "First Up" cause of trip.
State-of-the-art digital technology throughout, with quartz-controlled Loss of Mains detection. True RMS measurements.
Loss of Mains Protection
KCG595E will provide the following protection:
- 2 stage Over and Under Voltage
- 2 stage Over and Under Frequency, two levels
- Rate of Change of Frequency (ROCOF, df/dt)
- Vector Shift (step phase angle)
- Voltage Imbalance
Generator Island Protection
KCG595E will provide the following protection:
- Over and Under Voltage
- Voltage Imbalance
- Over and Under Frequency
Synchronisation Enable Function
KCG595E also includes a synchronisation enable relay output, which will safeguard that the generator voltage and frequency are within the generator island mode set-points prior to synchronising to busbar or to mains.
