Ground Potential Rise Hazard Monitoring
With the tremendous increase in demand for power and expansion of infrastructure comes greater risk for more workers on the job site. Although workers are thoroughly trained, high voltage accidents still take place. Even well-trained linemen may not often realize that nearby energization and faults in substation or transmission lines can result in dangerous conditions. Concern over these risks is what spurred The GroundHound inventors to find solutions to prevent shock incidents caused by the phenomenon of “Ground Potential Rise” (GPR), “Earth Potential Rise” (EPR), also called “Step & Touch” – “step voltage” – “touch voltage” and “transfer touch voltage.” Their goal was to give high voltage workers on the ground warning of unexpected dangerous events. Ours was to build it to be accurate, safe to operate and provide high voltage workers with the best real time situational awareness possible.
