On-line Monitoring System of Lightning Arrester

Metal zinc oxide arrester is one of the key equipment of power equipment, the leakage current flowing through the arrester is an important index to measure the insulation degree of the arrester. The JCQ-485 series arrester on-line monitoring device can realize real-time monitoring of the insulation condition of the arrester through real-time on-line monitoring of the full current, resistive current, lightning strike times and lightning strike time of the arrester. At the same time, the potential failure of the metal zinc oxide arrester can be found in time by analyzing the monitoring data, which provides an important maintenance basis for the condition-based maintenance. According to the needs of the field, this product is designed for the remote meter type and sensor type two specifications.
