what is the earthing condition between earth & neutral.
Answer Posted / glen
if you see the voltage level between earth and neutral is
approx 2to3v
this is becoz
earth is at potential zero
but neutral is not at exact zero
it is zero volt with respect to phase but is floating with
respect to earth

What is the need of earthing transformer for delta side of a transformer. (Think of a line section between a star/delta transformer at a grid substation and delta/star transformer at a village. An earthing transformer is there at the delta side of the star/delta transformer at grid substation). As there are no ground reference there will not be fault current if a one phase is grounded. Further L-L phase will be sensed by the primary side of star/delta transformer as a L-G fault. So why an earthing transformer is required at delta side
