High Voltage Detectors

High Voltage Detectors

High Voltage Detectors (HVD’s) 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.

Each High Voltage Detector standard kit comprises the following components housed within a purpose designed ABS heavy duty carry case:

  • High Voltage Detector (HVD)
  • Contact electrodes (Y and Hook)
  • Bowthorpe Rod Adaptor
  • Polymer cleaning kit
  • Instruction Manual

High Voltage Detectors 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 LED’s and audibly with a high intensity buzzer. This ensures clear indication even in conditions of bright sunlight and high background noise.

The voltage setting to trigger activation (or threshold setting) can be set in accordance with IEC standards or in consultation with the user where detectors are used on a range of system voltages. All detectors have the facility to self check before and after use.

Bowthorpe, Karl Pfisterer, and Universal Starwheel types rod adaptors are available for connecting to various operating poles. Three sizes of aluminium hooks are available in 40, 60 and100mm, alternatively a straight 40mm stainless steel stud electrode, or a Y contact electrode can be supplied.

To distance the detector away from any source of interference four sizes of electrode extensions are available in 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).

Designed to comply with relevant IEC standards, HVD’s are available for use on system voltages up to 275kV. A wide range of models are available to cover most distribution and transmission voltages used throughout the world.
