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
