Ans: Transformer secondaty sholud have neutal point. This
we brought from earth. neutral point is earthed and
connected to T/F. for this we required one earh pit. and
for body earthing we should have another earh pit.
structure earthing for this another earth pit.
For an equipment we required only one earth pit for body
earthing and electrical accessories earthing( like
motors,switch gear, electronic instruments).
