EGP 1 Basic Generator Protection Equipment Set
Training contents:
Time overcurrent protection
• Operating response and release response for single-pole
and three-pole faults
• Determining the tripping times
Unbalanced load protection
• Operating and release response to unbalanced load
• Determining the reset ratio and the tripping times
• Determining the relay characteristic TA = f(unbalance)
Reverse power protection
- Synchronisation of the generator to the power grid
- Detection and disabling of the generator in the case of reverse power flow
Overvoltage and undervoltage protection
- Reactions to phase failure
- Detection of starting and tripping times
Stator-earth fault protection
- Detection of system voltages under normal operating conditions or stator-earth fault occurrence
- Measurement of tripping times
- Calculation of the earth-fault current
