Ferrite Ground Current Sensor

Purpose: [MGB] CESR Quad Bus has been tripping on ground fault. The bus is routed with the +/- bus bars running parallel. A measure of the net flux around both bus bars should be proportional to their net current. With no ground fault this should be zero. Use a ferrite around the pair, with a gap, and a hall sensor installed in the gap.
