Abstract

In view of the phenomenon that the leakage current in the underground power grid fault is caused by the decrease or damage of the insulation of the AC distribution line to the ground, the UA level high-precision current sensor with zero magnetic flux current sensing technology is developed, and the harmonic analysis method with windows is adopted to effectively eliminate noise, thus ensuring the accuracy of data collection. The leakage current of underground electrical equipment is monitored in real time to realize the early warning of insulation failure.
