WebDefine ground fault. ground fault synonyms, ground fault pronunciation, ground fault translation, English dictionary definition of ground fault. n. An electrical fault in which current completes the circuit by improper grounding, posing a shock hazard. 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. WebWhen a ground fault occurs, the pathway to ground immediately becomes unrestricted, with no resistance, and this causes an enormous sudden increase in current flow.
