WebNeutral to earth voltage (NEV) specifically refers to a difference in potential between a locally grounded object and the grounded return conductor, or neutral, of an electrical system. The neutral is theoretically at 0 V potential, as any grounded object, but current flows on the neutral back to the source, somewhat elevating the neutral voltage. WebElectric potential difference, also known as voltage, is the external work needed to bring a charge from one location to another location in an electric field. Electric potential difference is the change of potential …

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 telecommunication line) bonded to a remote ground potential (such as the Central Office/Exchange) enters the area subject to GPR, the conflicting difference of potentials can create significant risks. High voltage can damage equipment and present a danger to personnel.
