1)What should be the distance of earth from a building? (Chemical Earthing) (ESE Lightning Arrester) 1) An Earthing electrode should not be situated within a distance of 1.5 m from the building whose installation system is being earthed. (Chemical Earthing Supplier in India)(Tercel Lightning Protection in India) 2) What should be the Earth Resistance of an Electrical Installation System? Earthing resistance is defined as the Earthing resistivity between actual earth and the earthed body of the installation. Resistance is nothing but the resistance of the path attaching the body of the installation to the actual earth. The earthing resistance should be low enough to carry the current to the earth to ensure proper operation of protective relays or blowing of fuses associated to the installation. The earthing rout consist not only the earthing continuity conductor but also it includes soil in between the end of the earth continuity conductor inside the ground and actual earth. As the resistivity of soil depends upon its moisture, it varies time to time throughout the year. As a result earth resistance of an installation is not constant throughout the year, it varies with weather conditions. Earthing resistance of an installation is minimum in rainy season whereas it is maximum in dry season. Although this resistance varies time to time, but there are some standards of maximum allowable earth resistance. 1. Earthing resistance of a large power station is 0.5 ohm 2. Earthing resistance of major power station is 1.0 ohm 3. Earthing resistance of small substations is 2.0 ohm 4. Earthing resistance for all other cases is 5 ohm. This should be noted that, the resistance between any point on the earthed body and the earth pit should be less than 1 ohm.
