The GroundHound - Site Safety Warning System Ground Potential Rise (GPR) Monitor
Description: Site Safety Warning System Ground Potential Rise (GPR) Monitor
The Multi-function GroundHound – Site Safety Warning System is an instrumentation system designed for the protection of linemen on a work site. The system consists of a Sensor Unit and a Handheld Unit communicating via wireless protocol. The sensor unit, a self-contained ruggedized case that is safety yellow, is connected to the worksite ground and lies 20 feet away from it. The sensor can be set to monitor and alarm on three levels of hazard, utilizing an emergency flashing light and an audible alarm which
Transmission line workers are in constant danger of Ground Potential Rise, Step and Touch Potential and Transient spikes in voltages.
Field tests show that only 1 amp of current (500 ohms or higher) can produce a 500 volt potential.
