S&F and testing on commissioning of Advance conductive compound based chemical compound technology with upgraded high tensile low carbon steel rod as per UL 467 and as per BS 7430 with copper Coating 250 microns. Earthing system confirming to IS:3034. The ROD should 17.2 mm & 3 Meter length with rod to tape clamp, CR 125 (type A) additional protection of the terminal. Chemical compound should be The highly Conductive Compound as per BSEN 50164-7with 25kg each bag & resistivity should be 0.05 ohm meter. The job includes digging the pit and refilling the same by forsake Back Fill Compound (Ground Enhancer), the BFC should be eco friendly it should not contain environmentally hazardous material/metal having mixed with 3:1 cement , a conductive concrete is formed. The earth pit should provided with a light weight inspection pit cover PT -205 for protection and safe guard of terminals. In areas where soil condition is bad Good earth is to be arranged to fill the excavated pits by mixing forsake a convenient and permanent solution by adding with 3:1 ratio chemical compound with the earth electrode is the main component of the earthing system which is in direct contact with the ground and thus provides a mean of releasing or collecting earth leakage currents. The material should have good electrical conductivity and anti corrosion property in wide range of soil conditions. Make : ABB Forsake as per RB 336. Each earth pit should contain:- 1.) 1 no. copper bonded high tensile low carbon steel, 17. 2 mm dia , 3 meter length. 2.)
