through the real-time on-line monitoring of the full current, resistive current, capacitive current, lightning strike times and lightning strike time of the arrester, the system can realize real-time monitoring of the insulation condition of high-voltage electrical equipment. at the same time, by analyzing monitoring data, the system can timely find the potential fault of the metal zinc oxide arrester and provide an important data basis for condition maintenance, a strong and reliable guarantee for the safe, reliable, stable and economical operation of the power system, and reliable equipment insulation information and scientific maintenance basis for operation and maintenance personnel, so as to to achieve the purpose of reducing accidents, lengthening the maintenance interval, reducing the number and time of outage maintenance, and improving the utilization rate of equipment and the overall economic benefit.
(1) jc-32 is a wired arrester leakage current monitoring system, using the core-penetrating sensor to monitor the arrester leakage current in real time;
(2) jc-32w is a remote digital meter for leakage current of wireless arrester, which monitors in real time the full current, resistive current and lightning strike times of the arrester, and works with the aggregation nodes to achieve wireless data upload.
