ActiveGuide to UV imaging detection of electrical equipments in high altitude regions—Part 2: Transmission lines
高海拔地区电气设备紫外线成像检测导则 第2部分：输电线路
Application Summary AI generated
This standard provides technical guidelines for using ultraviolet (UV) imaging to detect corona discharge and surface defects on high-voltage transmission lines operating in high-altitude regions (typically above 1000 meters). It is applied by electrical utilities and maintenance teams to conduct non-contact inspections of insulators, fittings, and conductors, where reduced air density at altitude increases the risk of corona activity. The standard specifies detection procedures, environmental condition requirements, and defect classification criteria to ensure reliable assessment of line insulation performance in these challenging environments.
