IBCG Ground Directional Overcurrent Relay

IBCG Ground Directional Overcurrent Relay

The Type IBC directional overcurrent relays are employed primarily for the protection of feeders and transmission lines in applications where single-phase relays are desired or required.

The Types IBC and IBCG relays consist of two units, an instanta-neous power-directional unit (bottom) of the induction-cup type, and a time overcurrent unit (top) of the induction-disk type. The direc-tional- unit contacts control the operation of the overcurrent unit (directional control).
