Abstract
A ground fault detecting device includes a signal generating unit that generates a signal for ground fault detection, a signal supply unit that supplies the signal for ground fault detection to an object of ground fault detection a signal processing unit that executes signal processing of a detection-target signal including at least the signal for ground fault detection obtained from the object of ground fault detection a signal separating unit that extracts the signal for ground fault detection from an output signal of the signal processing unit, and a ground fault detecting unit that detects occurrence of a ground fault in the object of ground fault detection based on the signal for ground fault detection output from the signal separating unit. The signal supply unit and the signal separating unit are configured by passive elements. The signal generating unit and the signal processing unit are configured as active circuits.
