  • Page 3 V-W TCH ® PERSONAL VOLTAGE DETECTOR Operating & Instruction Manual GENERAL DESCRIPTION ......4 POINTS TO UNDERSTAND BEFORE PROCEEDING .
  • Page 4 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 • Always use proper high voltage procedures, including personal protective equipment, when working near or around high voltage equipment or conductors. • Do not rely on the detector as your sole source of high voltage detection. Risk of electrocution is inherent in or around high voltage.
  • Page 7 WARNING NOT FOR USE BELOW 2400 VOLTS AC. OPERATIONAL IMPAIRMENT If the detector is used in a manner not described in this instruction manual, the protection and effective operation of this equipment may be impaired. The detector will not detect DC voltage or stored charge such as in charged capacitors or underground cable.
  • Page 8 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 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 When properly worn on the front of the body, as shown, and with the user facing a waist height energized conductor, such as a terminal on a pad mount transformer or switch, the detector will start to alarm about 10 feet from a 7kV conductor. If the user were to approach this energized terminal Adequate...
  • Page 11 distance. The reverse is also true; the detector may alarm due to the very close proximity of low voltage when the user walks past a typical factory machine such as a running drill press, an office computer terminal or a desk lamp. It may even alarm if it is placed up against a typical 120 volt wall outlet.
  • 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 Warning Distance at First Beep 3 ft. WARNING: 2 ft. Conductors lying 1 ft. on the ground or very close to it will Warning Distance Reduction result in reduced warning distances. Conductors of different phases in close proximity will also reduce warning distances due to field cancellation effects.
  • Page 14 outage and the delta system can continue to operate with this grounded phase. If this phase is grounded as a result of a downed conductor or other storm damage, it may be grounded only temporarily and could become reenergized if moved or disturbed. 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 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...
  • Page 18 When the V-Watch Personal Voltage Detector is in use with a good working battery, it is always on, always ready to warn of potentially hazardous high voltage. The battery life is approximately six months of continuous use or two years in storage. When the job requiring the protection of the detector for the user is completed, the detector should be closed by pushing down on the top.
  • Page 19 the top up. A successful self test is indicated by a tone series and flashing lights. 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. Do not use harsh chemicals or solvents.
