Ground Fault Relay Characteristics
Note:
The range for an operating time of 0.3 s is 0.15 to 0.45 s and the range for an operating time of 0.8 s is 0.6 to 1.2 s.
■
ZCT (Zero-phase Current Transformer)
Note:
Do not connect ZCT output terminals k and l to ground. Doing so may result in damage to the Relay.
