1 Research BackgroundMetal - oxide surge arresters, sealed in cabinets, bear system voltage continuously, risking aging failures, even breakdowns/explosions causing electrical fires. Thus, regular inspection/maintenance is needed. Traditional 3–5 - year - cycle detection (power cut, arrester removal for tests; reinstallation if replaced) poses safety risks and faces space/environment - based standard - grasping difficulties.2 Monitoring Principle of 10kV GIS Cabinet Surge ArresterTo en

1. Current Situation and ProblemsLow - voltage overhead cables often suffer insulation damage. Urbanization and infrastructure construction expose them to complex environments (construction, severe weather like strong winds/rains causing scratches or impacts, animal damage), easily breaking insulation layers. Long - term operation also degrades insulation due to aging, corrosion, and prolonged sunlight—e.g., cables in old communities age and crack, raising failure risks.Existing restor

With the rapid development of power systems, electronic voltage transformers (EVTs), as key measurement devices in power systems, their performance stability and reliability are crucial for the safe and stable operation of power systems. The electromagnetic compatibility (EMC) performance, as one of the core indicators of EVTs, is directly related to the ability of the device to work normally in complex electromagnetic environments and whether it will cause electromagnetic interference to other
