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 source. Ground potential rise is a concern in the design of electrical substations because … WebNov 7, 2024 · An earthing grid is made up of a number of rods connected together by copper conductors. Earthing grid is also known as the earthing mat. It looks like a mesh of conductors. The purpose of earthing grid is to reduce the overall grounding resistance. It also helps in limiting the potential gradient. It is a part of the electrical earthing system.
