explain why tap changer is always connected to high voltage
winding side of the transformer.
Answer Posted / d4
The HV windings are placed on the LV windings, so it is easy
to take tappings from the HV side. Also the currrent in the
HV side is less than that on the LV side; this helps in
reducing the arcing which takes place as a result of tap
changing.
