摘要
The present invention is a ferromagnetic material in a super-precision grounding detection system with Option #1 IEC61850, Option #2 Modbus AGFR, Option #3 RS-485, Ethernet TCP/IP, and DGPS RS-485 functions in an energy storage device and a grounding detection system for an in-house switchboard High sensitivity that can accurately measure a few mA of DC low current through the output of the main coil by amplifying the induced electromotive force induced in the auxiliary coil separate from the main coil in the core and changing the oscillation period of the spherical plate of the square wave oscillation circuit A high-precision grounding detection system for energy storage devices and on-site switchboards that can be used to prevent large accidents such as fires and short circuits that may occur later as it can detect ground faults and leakage currents that need to be detected at several mA through a DC current transformer. provides
