Ground current detector
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. WebTo test a DC circuit ground wire, remove it from the appliance to which it is connected, such as the radio, heater fan or cigarette lighter. Set your multimeter to 20 volts DC. Touch one probe to the end of the ground …
