Electrical power transformers training for electrical engineers

       Course Fee: INR 24,000/-     Course Duration: 2 Months

Transformers are commonly used in applications which require the conversion of AC voltage from one voltage level to another. There are two broad categories of transformers: electronic transformers, which operate at very low power levels, and power transformers, which process thousands of watts of power. Electronic transformers are used in consumer electronic equipment like television sets, VCRs, CD players, personal computers, and many other devices, to reduce the level of voltage from 220V (available from the AC mains) to the desired level at which the device operates. Power transformers are used in power generation, transmission and distribution systems to raise or lower the level of voltage to the desired levels. The basic principle of operation of both types of transformers is the same. In this chapter, we will first review some of the basic concepts of magnetic circuits, which are fundamental building blocks in transformers and electric machinery. In order to understand how a transformer operates, we will examine two inductors that are placed in close proximity to one another. The concepts of such magnetic coupled circuits will be extended to the development of transformers. After understating the relationships between voltages and currents, we will look at some practical considerations regarding the use of transformers.
