Abstract

This paper deals with the influence of thermal stress on the transformer lifetime. Transformer lifetime is influenced largely by overheating of windings and then the insulation ages and reduces its electrical insulating properties. Proper placement of electrical transformer parts can help to ensure the more uniform distribution of temperature field and to increase the transformer lifetime.
