There are two ways of cooling the transformer:
First, the coolant circulating inside the transformer transfers the heat from the windings and the core entirely to the tank walls and then it is dissipated to the surrounding medium
Second, along with the first technique the heat can also be transferred by coolants inside the transformer.
The choice of method used depends upon the size, type of applications and the working conditions.
