How to design power transformers efficiently?

Simon Guicheteau ; CEDRAT

Abstract

Nowadays power transformers need to optimise their efficiency to ensure that a minimum amount of losses is generated by various physical phenomena. Finite element studies allow transformer designers to accurately analyse various losses (Joule losses, iron losses, stray losses) in order to enhance transformer performance. There are a few steady state and transient tests which allow the assessment of electrical and mechanical constraints that a power transformer will have to endure during its life cycle. In addition, thermal analysis can complete these studies to detect and prevent hot spots on the tank or in the windings.
