WHAT IS EDDY CURRENT LOSS?
WHAT IS HYSTERESIS LOSS?

Answer Posted / raj

hysteresis loss: some material had character like keep
storing magnetic enery in that. so loss of flux will occur.
this is hysteresis. this can be neglect by using silicon
steel.having high permiability.

eddy loss: current flows in metal creats its own flux and
crets a emf in it. this is back emf or eddy current .this is
due to main flux , this new back emf produses the flux and
oppose the main flux. hence loss occur.
this can be overcome by proper lamination.

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
