If the earthing is good ,the bulb will burn at almost full
phase voltage in case of AC.In DC ,the same if one polarity
is earthed, but if the ground potential is at +/- zero volt
by midpoint earthing,the bulb gets the half the full
voltage.

we have earthmat at 110KV substation.we would like to take earth resistance.b some says that by connecting earth megger terminals (C1,P1) at middile point of earthmat (at riser) will cause voltage gradient at other earthmat nods and dont get exat earth resistance.when connecting at end nods will get exat value . is it correct .please explain
