Wireless High Voltage Detector

The wireless high voltage detector will check the status of high voltage line whether it is OFF, Live or any induced voltage. The wireless technique will assist in high voltage isolation between the HV sensor unit and the detection display unit for better visualization for HV detection, HV safety and high raise height OH lines for high voltage levels up to 765kV.
