Leakage current sensor is a closed-loop small current sensor developed based on the principle of magnetic flux gate and magnetic modulation technology. It is divided into DC leakage current and AC leakage current. It has good stability in measuring small currents and high insulation value between primary and secondary.

Widely used in insulation leakage detection of power grid plants, current detection of signal control systems, and other applications that require current difference measurement, it is used to solve the problem of power plants, substations, and all industrial enterprises that use DC control systems, such as power, chemical, telecommunications, railways, etc., which have requirements for the safe operation of DC systems. It monitors the status of DC system leakage current, especially the monitoring of small currents in DC system leakage current, timely and accurately eliminates DC system grounding faults, eliminates hidden dangers of DC system grounding faults in advance, and avoids the harm caused by simultaneous grounding of two points.
