Power Transformer Parts and Functions

INTRODUCTION

A electrical device that transfers electrical energy between two or more circuits through electromagnetic induction is know as power transformer. Power transformers are used to increase or decrease the alternating voltages in electric power applications. Electromagnetic induction produces an electromotive force within a conductor which is exposed to time varying magnetic fields.
