g systems shall again be interconn ected as network.The earthing system shall be provided to have overall network earthing resistance less than one ohm. Soil resistivity test through approved agency shall be carried out by the contractor at each location and the system shall be designed accordingly. The ring earthing system around each building shall be laid at distance of approximately 1.5 from the building and at depth of approxi mately 0.8m. The ring shall be bonded below the ground at intervals to the building teel structures, reinforcement of building column and also to pipes, wherever hey are crossing as far . all further be connected at inte rvals to earthing electrodes as per the requirement to achieve combined earth esistance of less than one ohm. For the purpose of dimensioning the earthing lines/conductors or main earthing ring/earthing grid, the duration of the earth fault current sha ll be taken as 1 sec. For different floors within building, localized ground mats hall be formed and 1 of 1 INDRADHANUSH GAS GRID LIMITED TECHNICAL SPECIFICATION FOR NATURAL GAS COMPRESSOR STATION FOR NORTH EAST GAS GRID PIPELINE PROJECT ______________________________________________________________________________________________ TS NO.: MEC//2UU/0/2/0 Electrical system Chapter-0.0 2, MECON Limited, All Right Reserved Pag 2 of 2 connected to the ground earthing ring through vertical risers. The earthing mat shall be common to both power and lighting installations. The ground mats so formed shall be covered with floor finish. For protective earthing separate conductor shall be used for fl ow of earth fault current as elaborated below. The LV side neutrals of the Powe and distribution transformers shall each be connected to two separate earthing electrodes. Both the earth lectrodes shall also be interconnected with GI earth Strip
