Answer Posted / shan80
there is no necessery to use 1250 vcb for 50A u can use
630A vcb for that load.1250A is only manifaturing capicity
630A vcbs also available and these rating r standard. 1250A
rating is only normal current rating not shot circuit rating

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
