HVD high voltage indicator is adapted for indoor electrical panel, used in MV / HV switchgear. It is connected via internal wiring to capacitive sensors inside the switchgear. Rated voltage 3~40.5kv, operation frequency 50Hz network to display the electrifying situation of the high voltage loop where the device is mounted.
This integrated voltage detecting system is used for continuous operation. The condition "voltage present" is displayed by three LED indicator.
