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.

We have overhauled OLTC and checked up all contact diverted switch and cleaned up the accumulated dirt and OLTC is a busy part of power transformer.
