This book describes many aspects of power transformers. And it mainly provides valuable knowledges such as two deals with power transformer construction, different types of transformers and connections, power transformer core modelling, and the low-frequency and mid-frequency modelling of transformers.

Moreover, it also introduces a new method for high-frequency modelling of transformer which can attract many students learning the power transformer research field. The goal of this book is to educate the postgraduate students and engineers about principals and modeling of the transformers
