Product Description

Abstracts

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

It is widely applied to insulation leakage inspection and current inspection of signal control system in power grid and power plants, as well as other applications requiring current difference measurement. It is adopted in power plants, substations and all industrial enterprises that use DC control system, such as electric power, chemical industry, telecommunication, railway and other departments that have requirements for the safe operation of DC system, to perform monitoring the ground leakage current state of DC system, especially the monitoring of the low current state in the ground leakage current by DC system, eliminate the ground fault of DC system timely and precision, and eliminate the hidden trouble of DC system grounding in advance to avoid the harm caused by the simultaneous grounding of two points.
