Answer Posted / habib
Transformer primary is not in star we can say for all
transformer HV side should be in star,because in star Phase
voltage will be reduced by 1.732 times to delta,so it
reduces the insulation requirment.
Second in Generating station transformers load side that
means the side which will be connect to the grid will be in
star,because grid distubances should not circulate in
transformer if it is in delta distrubances circulate in the
transformer which reduces the transformer performance

please tell me when we start motor without load in star or delta connection whose current above condition,pl write formula
how much UPS neutral erath leakage current.
A 230V dc shunt wound motor has an armature resistance of 0,15Ω.When operating on no load at 650 rev/min the armature current is 6A . The motor takes a full load current of 85A. Calculate the full load speed if the field flux is (i) maintained constant (ii)reduced by 0,03
