Abstract :
In this work, a study of the parameters that affect the breakdown voltage in dry-type transformer is performed. The effect of the high operation temperatures of the transformer on the voltage breakdown in the insulating supports is investigated and the electric field distribution on different profiles of these supports is modeled using Finite Element Method (FEM). A design of the insulating support that can help to reduce its length without increasing the possibility of breakdown is discussed.
