what is the formula for 3 phase motor starting cureent
deatials
3phase 148A delta 415v, efficiancy 94%
can we run the motor with 200A incoming supply
Answer Posted / birinchi narayan boruah
It depends upon designed parameter of the motor. Generally
All 3 phase Induction motors take starting current 3 to 5
times of the full load current. 200 Amps incomer can be used
for the same but its better if you go for higher 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
