In an electrical installation an earthing system or grounding system connects specific parts of that installation with the Earth's conductive surface for safety and functional purposes. The point of reference is the Earth's conductive surface. The ch

GI Earthing Vs Copper EarthingAs per IS 3043, the resistance of Plate electrode to earth (R) = (r/A) X under root(P/A).Where r = Resistivity of Soil Ohm-meter.A=Area of Earthing Plate m3.The resistance of Pipe electrode to earth (R) = (100r/2πL) X lo
