BASIC TRANSFORMER PRINCIPLES
Transformer has been one of the most significant inventions of human kind in relation to electricity. Its construction became a breakthrough to all other discoveries that has elevated man kind's way of living. At present, it is almost unimaginable to think if transformers have not even been around. Two key principles has been the main reason for its existence; that a magnetic field can be produced from electric current termed as electromagnetism and the other one is that voltage can be induced at the ends of a coil whenver a changing magnetic field within a coil of wire also termed as electromagnetic induction. Today, various forms of transformers exist at our disposal, from the smallest size to the gigantic forms also known as power transformers all for the purpose of serving man's needs.

Before we discuss the losses that exist in the transformers found in our power system, let us first have the time to review its basic principles of operation. With this we can be able to refresh minds in line with the things we learned about transformers in our academic days.
Our review will focus more on the preliminary considerations when refering to a transformer, its construction, what is an ideal transformer, analysis of its equivalent circuits, and other topics relating to it. A short presentation from Dr. Gleb V. Tcheslavski will discuss these topics.
