Electrical Testing
Generator Protection Relay, Transformer Protection Relay, Feeder Protection, Primary Injection Test, Secondary Injection Test, Pickup & Dropoff.
A protective device that monitors the generator’s operating conditions and isolates it during faults or abnormal conditions to prevent damage.
- Protects against overcurrent, over/under-voltage, over/under-frequency, and reverse power.
- Detects faults like rotor earth faults, stator winding faults, and loss of excitation.
