Heat dissipation is a pronounced problem in transformers as transformers are enclosed devices and due to no
rotating part in transformers. Any solid body with losses taking place in it generates heat inherently, as, any form of
energy loss in a body is dissipated in the form of heat. The loss can be either magnetic loss, due to contact of fluxes or hysteresis loss, or ohmic loss, due to the current passing through a conductor and the resistance being given by it or mechanical loss, due to moving parts and the friction between the surfaces in contact. The heat generated in any body is dissipated to the surrounding media and ultimately to the ambient. As the transformer start heating up, the
winding insulation may start weakening and the value of the dielectric constant of the mineral oil reduces from the
standard value. Investigations are carried out to analyze the amount of temperature raise during the transformer functioning and designing auto cooling system.

Keywords: TEC, Heat Exchanger, Power System, Transformer, Auto cooling.
