Surge Arresters Need To Be Inspected And Maintained Regularly.

As a core protection device in substations and transmission lines, the technical condition of the 11 kv lighting arrester directly affects the safety of the entire power grid. As operating time accumulates, the internal components of the 11 kv lightning arrester will age, the sealing performance will gradually decline, and the leakage current parameters will drift.

Insulation resistance measurement can detect moisture problems caused by poor sealing. When the measured value changes significantly compared to the previous result, a characteristic test must be carried out immediately. The operation records of the discharge counter can reflect the working status of the 11kv 10ka lightning arrester during lightning activity, providing an important basis for judging the health of the equipment. Leakage current monitoring of zinc oxide 11kv lighting arrester is also crucial; abnormal increases in the resistive current component often indicate valve aging or internal defects.
