。[Claim for Utility Model Registration] A ground fault detection current that is a high-frequency power supply that is installed on the low-voltage side grounding wire of a power transformer and supplies a ground-fault detection current that is a current with a frequency different from the power supply frequency to this low-voltage side grounding wire. A ground fault detection magnetic field that is a magnetic field generated when the ground fault detection current causes a ground fault at a leakage point of the load device by searching around the supply device and the load device connected to the low voltage side of the power transformer. and a magnetic field detection unit that is a magnetic field sensor that detects the current leakage point of the load device, and the ground fault detection current supply device supplies the ground fault detection current to the low voltage side grounding wire. What is claimed is: 1. An earth leakage point detection device, comprising: an electromagnetic induction coil for inducing an electric current, and supplying a ground fault detection current to the low voltage side grounding wire by electromagnetic induction.
