Answer / pasang, avit, chennai

Tappings of the transformer irrespective of either
Distribution or power transformers are on the HT side due
to the following reasons.

1. The HT windings have more No of turns than the LT
windings so that the flexibility of Stepping up and
stepping down is easier with more tappings.

2. The tap changing is easy and safe considering the
Voltage level and also the requisite voltage level either
step up/down can be acquired

why we use taping of transformer on HT side?..

Answer / animesh pal

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...
