Grounding Studies

The main driver of a ground system study is to protect workers from “step potential” hazards, which result from currents that generate high enough voltages to become lethal at distances as short as one human step. To eliminate these hazards, Vertiv’s ERS engineers will do a grid and ground potential analysis and will perform other relevant measurements and modeling to optimize the design of a ground system to effectively shunt the fault current to the earth, away from workers and equipment.


  • Field acceptance testing, per NEC requirements, verifies proper installation and operation of your ground fault protection system
  • Bonding inspection identifies and resolves problems that can defeat ground fault protection or cause inadequate tripping
  • Sensor installation check eliminates false tripping that can occur with incorrect current sensor installation and wrong polarity
  • Relay testing ensures your system’s relay trips within manufacturer’s tolerance in order to provide adequate protection
  • Operations test of the overall system, including special features, verifies functionality that provides the needed protection


  • More confidence in your electrical infrastructure is achieved with periodic testing to verify the integrity of the grounding system
  • Improved protection for systems and people occurs as electric shock can be avoided
  • Fewer outages are possible as a study determines if your system adequately manages low-level arcing ground faults
  • Less nuisance tripping occurs when a study confirms functionality that complies with manufacturer, UL , and NEMA recommendations
  • Ensured compliance with safety codes and regulations occurs when studies are performed by experienced, NETA-certified technicians
