A Review on Transformer Design and Innovative Aspects of Optimization

Abstract

Transformer is the most costly and important component of power system. It is more than 100 years old technology. Technology has not changed drastically but the challenges are continuous increase in size and rating, competition in global market, accurate prediction of performance parameters, updating of design baseline and many more. Transformer design optimization (TDO) is a complex task in which designer have to ensure that the imposed specifications are met, while keeping manufacturing costs low. The research associated with design optimization is therefore more restricted involving different mathematical optimization methods. This paper presents review of research and development in transformer engineering and design optimization for the past 40 years based on more than 100 published papers, latest 10 transformer books and various national and international standards.
