  • Page 4: General Description

    GENERAL DESCRIPTION The V-Watch® Personal Voltage Detector detects the strong electric fields surrounding high voltage conductors and power distribution equipment. It is a small pocket size device worn on the outside of the clothing or other protective gear by users operating near power lines or high voltage equipment.
  • Page 5 The V-Watch Personal Voltage Detector detects electric fields. Make sure you un- derstand these points before proceeding: • Electric fields surround every energized AC conductor. • The closer you are to a conductor, the stronger the field will be. • Higher voltage means a stronger electric field and a greater warning distance.

  • Page 6: Safety

    • Do not rely on the detector as your sole source of high voltage detection. Risk of electrocution is inherent in or around high voltage. • Never contact high voltage with the V-Watch detector. • Always use proper high voltage procedures for testing and grounding.

  • Page 8: How It Works

    HOW IT WORKS The V-Watch Personal Voltage Detector works by sensing the presence of the electric field surrounding anything that conducts high voltage electricity and sounding an alarm. It measures the strength of the electric field; a higher voltage or stronger field will cause the detector to alarm from a greater distance.

  • Page 9: A Word About Electric Fields

    A WORD ABOUT ELECTRIC FIELDS Electric fields surround every energized conductor. The V-Watch Personal Voltage Detector measures the strength of these electric fields to warn the user when fields are strong enough to indicate the presence of nearby high voltage conductors.
  • Page 10 The V-Watch Personal Voltage Detector measures only the strength of the electric field. It cannot directly measure distance to the source of the electric field such as an energized conductor. The higher the voltage,...
  • Page 11 A metal fence or a growing hedge can cause a distortion of the electric field under these lines and result in high electric field strength near the ground. The V-Watch Personal Voltage Detector will provide an early warning of high electric...
  • Page 12 As an additional protection against false alarms from transient voltages, the detector has a built-in time delay and may take up to one second to emit an alarm warning of high voltage. For this reason, a user running towards an energized high voltage source may find the warning distance reduced.

  • Page 13: Limitations For Use

    Conductors of different phases in close proximity will also reduce warning distances due to field cancellation effects. Wearing the V-Watch Personal Voltage Detector in en- vironments such as substations or under transmission lines may result in the detector alarming continuously.

  • Page 14: Instructions For Use

    The V-Watch Personal Voltage Detector will not detect any grounded conductor, whether it is a grounded delta phase conductor, a guy wire or a pole ground.
  • Page 15 always wear in the direction of movement or work. Do not walk backwards or sideways when wearing the detector as it will not detect high voltage behind you or as effectively to the sides. Wear on the outside of all clothing.

  • Page 16: How To Wear It

    HOW TO WEAR IT The V-Watch Personal Voltage Detector should always be worn mid-torso on the front of the body and face in the direction of movement. Because it is sensitive to electric fields in front of the user, and to a lesser extent on either side, proper positioning is important.
  • Page 17 The detector provides an early warning of the proximity of potentially hazardous high voltage electricity and equipment. It will start to beep with flashing lights slowly as an electric field is first detected and will then beep faster, increasing to a steady alternating tone and flashing lights if the user continues to...

    If the self test is not successful, do not use the V-Watch detector and return it to the factory for service. CLEANING To clean, wipe with a damp cloth with water.
