Abstract
A system for detecting a high impedance fault in a phase conductor having a potential device connected to the phase conductor, the system including a signal injection device having an input from the potential device which detects a reduction in voltage at the phase conductor and outputs a first signal in response to detecting a reduction in voltage at the phase conductor and a signal receiver which receives the first signal and provides a second signal to an interruption device in response to having received the first signal to cause the interruption device to open the circuit to the phase conductor.
