WebEarth Potential Rise (EPR))The difference in potential which may exist between a point on the ground and a remote Earth. Formerly known as RoEP (rise of earth potential). Earthing Conductor A protective conductor connecting a main earth terminal of an installation to an Earth Electrodeor to other means of earthing. Earthing System WebApr 16, 2024 · When lightning strikes a cell tower, the large amount of lightning current injected and dissipated in the earth near the tower can cause severe earth potential rise (EPR). It can drastically increase voltage gradients in the earth, even finding its way through the neutral and the earth electrodes into nearby dwellings.
