Plug In Type High Voltage Detector

This high voltage detector(HVD) can affix (plug in) to any type of insulated HV hot stick (live line tool) before starting the maintenance works and check the HT & LT line status (Off, Live or Induced voltage any) through indication of LED & Buzzer. HVD can be removed (Plug out) from the hot stick and then the hot stick can be used for normal functionality in the maintenance/service.
