Earth potential rise - Wikipedia
In electrical engineering, earth potential rise (EPR) also called ground potential rise (GPR) occurs when a large current flows to earth through an earth grid impedance. The potential relative to a distant point on the Earth is highest at the point where current enters the ground, and declines with distance … See more Earth Potential Rise (EPR) is caused by electrical faults that occur at electrical substations, power plants, or high-voltage transmission lines. Short-circuit current flows through the plant structure and equipment and into … See more "Step voltage" is the voltage between the feet of a person standing near an energized grounded object. It is equal to the difference in voltage, given by the voltage distribution … See more In principle, the potential of the earth grid Vgrid can be calculated using Ohm's Law if the fault current (If) and resistance of the grid (Zgrid) are known. While the fault current from a distribution or transmission system can usually be calculated or … See more • Single-wire earth return • Stray voltage See more An engineering analysis of the power system under fault conditions can be used to determine whether or not hazardous step and touch … See more The US Occupational Safety and Health Administration (OSHA) has designated EPR as a "known hazard" and has issued regulations governing the elimination of this hazard in the … See more In itself, a ground potential rise is not harmful to any equipment or person bonded to the same ground potential.
