Description
The fully self-contained KCG595E provides precision generator island protection as well as protection against malfunction and human and operational hazards under loss ofmains conditions for either single phase or three phase 3-wire systems.

The DIN rail mounted digitally controlled unit meets the protection requirements for generators connected to mains supply, such as defined in the G59/3 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
    • 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.

      Note:
      The KCG59x accommodates the new DCode Review Panel's proposal for Vector Shift immunity up to 50°. Enhanced ROCOF protection now provides adjustable averaging filter and 500ms delay for full compliance with G59/3 Amendment 3 due to come into effect on 1st February 2018.
