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

compound, which lowers the contact resistance of the earth electrode to earth by over 60%. It produces low impedance to surges resulting in faster transient dissipation. It is RoHS compliant and has excellent shelf life. It performs in all soil condi
