Generator and Transformer Earthing Electrodes The frame of each generator, stationary motors and metallic parts of every transformers used for controlling energy should be earthed by two separate and yet distinct connections with the earth.Proper

(1) Unearthed Neutral Systems: In unearthed system there is no internal connection between the conductors and earth. However, as system, a capacitive coupling exists between the system conductors and the adjacent grounded surfaces. Consequently, t

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
