1) In hv side current is low .so used switches ,circuit
breaker will be cheaper even though bushing is required.
2) in lv side if no of turn is reduced max flux density
will be increased [E constant].As we want flux density to be
at knee point,so flux density will be in saturation
region,iron loss increase,temp rise increase,efficiency
decrease.But for hv side max flux density will be
decreased.so loss will be less...
