Metal-Oxide Arrester Fault Diagnosis based on Flexible Detection System

Metal-Oxide Arrester(MOA) is to limit the lightning overvoltage and operating overvoltage, and protect other electrical equipment from overvoltage damage. The fault diagnosis of MOA is very important to power system, traditional test methods has several factors to restrict the efficiency and accuracy. Based on the flexible detection, which is designed as a cyber-physical architecture for industry 4.0-based power equipment detection system, a new MOA electrified tester is developed. It can not only obtain the voltage signal in a safe and convenient way but also can technically eliminate the interference of the electric field around. The device can be used for all arrester electrified test occasions. It can greatly reduce the risk of measurement as well as significantly improve the measurement accuracy.
