Transformers can have tapping in both primary and secondary. When we talk of HT transformers, tapping are provided in the primary winding, this helps us in getting proper output voltage by changing the tapping whenever the HT voltage varies from the actual specified voltage.

Tap changer is a device which can increase or decrease the output secondary voltage by changing the turn ratio or Primary or secondary winding. Tap changer is generally installed on high voltage side of a two winding transformer due to low current in this side.
