Answer Posted / sanjeet swarnakar
if AC excitation is given then alternate north and south
pole is created on rotor field
the rotor move half cycle clockwise and half cycle anti
clockwise and finaly stop to rotate
due to this dc current is given to the rotor of the
syncroneous motor

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
