high-voltageswitchgear measurement tools detecting

Voltage detectors are used to check for the absence or presence of voltage on medium and high switchgear, transformers or overhead lines – electrical safety is imperative in all areas of power transmission and distribution at all voltage levels including MV, HV and EHV up to 400kV. If the power system is Live then a visual and audible signal will be heard and seen from the detector.
