Learn why having a Personal Voltage Detector may just save your life!
How they work
Personal Voltage Detectors (PVDs) are worn on the outside of your clothing, sometimes with a lanyard or on forms of fall protection gear. It detects electric fields or energized equipment in close proximity to high voltage systems. It also alerts its user to these dangers, providing more time to respond in emergency situations.
Features and specifications
Substation Safety published an article on V-Watch PVDs regarding features and specifications of these detectors that promote the optimal safety of on-site substation personnel. The following features and specifications are adapted from their article:
V-Watch PVD Features
- Electrically shielded
- Alerts workers to nearby high voltage
- Audible and visual alarms increase as workers get closer to the high voltage source
- Initial warning distance is about 7 feet (2.13m) from a 4kVAC conductor
- Warning distance increases with higher voltages
- New C-10FR carrying case lanyard – high-visibility safety green shielded material with an outer layer of flame resistant material (allows user to adjust to optimum mid-torso position)
- Storage case when the V-Watch is not in use
V-Watch PVD Specifications
- Factory Set at 50/60 Hertz sensing threshold (first beep).
- The V-Watch will only detect AC voltage.
- Do not use below 2400 Volts line-to-ground.
- 9V alkaline 1604A, IEC 6LR61. Life is 2 years
- 2400VAC line-to-ground and above
