In case of earth potential
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 from the … 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. See more In itself, a ground potential rise is not harmful to any equipment or person bonded to the same ground potential. However, where a conductor (such as a metallic … See more An engineering analysis of the power system under fault conditions can be used to determine whether or not hazardous step and touch voltages will develop. The result of this … 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 • Single-wire earth return • Stray voltage See more WebResults Away from the Equator.

Ground Potential Rise (GPR) or Earth Potential Rise is a phenomenon that occurs when large amounts of electricity enter the earth. This is typically caused when substations or high-voltage towers ...
WebThe gravitational field inside earth is given by, E= R 3GM ex, where x is the distance of the object from center. As the object moves to center x=0 and therefore, E=0 . The assertion is therefore correct. We know that E= mF= [M][MLT −2]=[LT −2] The reason is also correct. But the reason is not the correct explanation for assertion.
