WebAn earthing mat is a grounding system formed by a grid of conductors buried horizontally and provides a low impedance path for the earth's fault current to dissipate into the earth. The earthing grid present in the substation is an electrical connection to the earth at zero potential reference point. WebGround potential rise (GPR): The maximum electrical potential that a substation grounding grid may attain relative to a distant grounding point assumed to be at the potential of remote earth. This voltage, GPR, is …
