Designed for rotor earth-fault protection in the excitation circuit of synchronous machines
Detects insulation failures caused by mechanical/thermal stress, vibration, overcurrent or poor cooling
Helps prevent dangerous second earth faults which cause magnetic unbalance and rotor damage
Useful for generators with slip rings where coal dust reduces rotor insulation resistance
REK 510 injects 100 VAC via coupling capacitors into the rotor circuit
Works with a definite-time earth-fault relay to measure the resulting current
