For which purpose the temp. rise test of transformer is conducted?..

You see, when the current in a transformer increases, the
losses inturen increase because losses= I*I*R.

The Losses in a transformer is dissipated in the form of
heat. This is nothing but temperature rise. Hence, a
temperature rise test is conducted in order to maintain the
temperature of the windings and core within limits, and to
check the losses.

Hope that answers.
