WebGround Potential Rise or Earth Potential Rise (as defined by IEEE Standard 80-2000) is the maximum electrical potential that a (substation) grounding grid may attain relative to a distant grounding point assumed to be at potential of remote earth. This voltage, GPR, is equal to the maximum grid current times the grid resistance. WebCircuit ground versus earth. Voltage is defined as the difference of electric potentials between points in an electric field. A voltmeter is used to measure the potential difference between some point and a reference point. This common reference point is denoted "ground" and considered to have zero potential.
