An overview,

When the power transformer iron core is grounded at two or more points, there will be circulation inside the iron core, causing local overheating, serious will cause local burning of the iron core, and even make the grounding segment fuse, resulting in suspension of the iron core potential, generating discharge fault, seriously threatening the reliable operation of the transformer. The monitoring system can monitor the grounding current of transformer core and clip in real time, with strong anti-interference ability and high precision. The monitoring data can be transmitted to the background through communication, and the online monitoring and fault alarm can be realized by combining the background analysis software.
