The GRB200 low impedance differential relay for busbar protection is designed to provide very reliable, high speed and selective protection for various types of busbar system. The GRB200 can be applied for single, double and ring busbars with/without transfer busbar, one and a half busbars and four bus-coupler busbars. A phase segregated current differential scheme is employed, and a maximum of 64 three-phase currents can be input from feeders, sections and bus-couplers, which can correctly distinguish between internal and external faults even in the event of CT saturation.
