WebGround Fault Warning Indicator. This is an accessory item for use with GFR relays with interlocking circuitry. At approximately 30–50% of the relay pickup setting, the indicator switches separate 120 Vac control power to a lamp or relay, (not included) to give an indication of a ground fault. The indicator is rated 110/120 Vac 50/60 Hz for a ... WebOct 29, 2024 · A residually connected ground relay is widely used to protect medium-voltage systems. The actual ground current is measured by CTs that are interconnected in such a way that the ground relay responds to a current proportional to the ground-fault current. This scheme, using individual relays and CTs, is not often applied to low-voltage …
