Answer Posted / g. janakiraman
no off earth pits are decided by considering the total
fault current to be dissipated to the ground in case of
fault and the current that can be dissipated by each earth
pit.
normally the density of current for GI strip can be roughly
200 amps per squre cam. based on the lenght and dia of the
pipe used the no of pts can be finalised. this has to be
worked out.
