According to IS 3043 earthing pits can be connected together
but the Lightning arr ester , Transformer neutral should
not be connected together since there will be restriking
faults frequently.

how much value of resistance should connect to 15 kw, 6 pole 3 phase slip ring induction motor having RV-240, RA-42.
