WebMar 6, 2024 · The Earth Potential formula is as follows: Earth Potential = Soil Resistivity x Current / (2 x PI x Distance) Where Earth Potential is in volts, Soil Resistivity is in ohm-meters, Current is the current flowing into the soil from the grounding system, in amperes, PI is 3.14159… and Distance is in meters. WebIdeally, in an AC system, neutral and earth should be at the same potential. It means the voltage measured between the neutral and the earth should be zero. This current can be primarily because of the phase current imbalance. The magnitude of this current is a fraction of phase current or in a few cases even double of the phase currents.
