JC-OM200A Transmission Line Lightning Arrester Online Monitoring System

JC-OM200A transmission line lightning arrester online monitoring system (hereinafter referred to as this system) is a new high-tech product developed by our company for the needs of the power system. The current detection of the system adopts a single-turn through-core current sensor to achieve full isolation () sampling method without residual voltage, advanced microprocessor technology and unique transient parameter testing technology for linearization and calculation, and the measurement results Digital wireless transmission via GPRS/GSM: The system has extremely high reliability and safety and relatively low price, so that the system can be installed in each group of MOA arresters for real-time detection, realize centralized monitoring, and effectively improve the performance of line arresters. The inspection efficiency reduces the labor intensity of the inspectors. Achieve accurate and timely grasp of the health status of operating equipment, so that operators can grasp and deal with potential accidents in advance, and ensure the safe power supply of the power grid.
