"WebThe ground detector circuit makes a connection between the rotor ground and the excitation circuit, usually on the negative terminal as shown here. A small DC voltage is injected across this connection, and the current flow through the circuit is measured. If a ground fault, R L, occurs, a current will flow through the ground detector circuit.
