Comprehensive Status Smart Sensor

WS-CJF-DACSW-112

WS-CJF-DACSW-112 comprehensive status smart sensor detects environmental temperature and humidity, UHF radio wave signals, transient ground voltage pulse signals, ultrasonic vibration frequency signals, etc. to monitor partial discharge defects and temperature and humidity changes inside the switch cabinet. At the same time, it can detect surface discharge, corona discharge, tip discharge, and insulator surface and internal discharge, and comprehensively locate the partial discharge power source.
