Chapter Abstract:

Transformers are used to change ac voltage levels, as well as to provide galvanic isolation between circuits. Single‐ and three‐phase transformers are extensively employed in the world's power distribution system. This chapter considers the design of single‐phase power transformers. It reviews the classic transformer T‐equivalent circuit and also considers its use in steady‐state phasor analysis. The chapter focuses on single‐phase transformers. Single‐phase transformers are often classified as being either core type or shell type. The chapter discusses transformer performance considerations such as the calculation of transformer parameters, regulation, magnetizing current, operating point analysis, and inrush current, all in general terms. It also focuses on one specific class of transformer, develop an Magnetic Equivalent Circuit, and ultimately a design approach. Core loss is a significant contributor to overall transformer loss and dominates no‐load losses. In the case of high‐frequency transformers, high‐frequency conductor losses such as skin effect and proximity effect can become important.
