The ZH480-S Corona Detection Camera is a bi-spectral handheld imaging system combining ultraviolet and visible light channels for real-time corona visualization under daylight conditions. Its solar-blind sensor enables accurate inspection of partial discharge in substations and transmission networks. Equipped with auto-report, auto-naming and threshold alarm functions, the device simplifies field recording and maintenance documentation.
