Edgcumbe High Voltage Detector (HVD)

High Voltage Detectors (HVDs) are widely used throughout the electricity industry to determine that high voltage lines are de-energised prior to work being carried out, thus ensuring safety of personnel. Designed to comply with relevant IEC standards, HVDs are available for use on system voltages up to 275kV. Each HVD standard kit comprises: High Voltage Detector (HVD), contact electrodes (Y and Hook), rod adapter and polymer cleaning kit.

HVDs are battery operated electronic contact devices that give clear indication of the status of the line under test both visually, by means of super-bright LEDs, and audibly with a high intensity buzzer. All detectors have the facility to self check before and after use. To distance the detector away from any source of interference four sizes of electrode extension are available in lengths of 100, 250, 650 and 1000mm. In addition to the self test facility an external battery operated proving unit is available to check the completely assembled kit (threshold voltage dependent).
