Answer Posted / vishal ingle
we can calculate power factor using formula
P = SQRT(3)* V * I * COS(PHAI)
but for deciding whether leading or lagging p.f we need
complex power
i.e. KVA = KW + j*KVAR or KVA = KW - j*KVAR

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
