JC-TLOM200/MOA Transmission Line Lightning Arrester Online Monitoring System
JC-TLOM200MOA 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 this system adopts a single-turn through-core current sensor to achieve full isolation and no residual voltage sampling. Advanced microprocessor technology and unique transient parameter testing technology are used for linearization and calculation, and the measurement results are passed through GPRS /GSM for digital wireless transmission: This 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 inspection efficiency of line arresters , Reduce the labor intensity of 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.
