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
