Transformers
INTRODUCTION A transformer transfer wlectrical energy from one circuit to another through intuitively coupled conductors. It is widely used to change the voltage and currents can either be increase or decrease as per required. A transformer has no moving parts. WORKING PRINCIPLE OF TRANSFORMER A transformer is a static device wich means of wich electric power in one circuit in transformed to another circuit without a change in frequency. CONSTRUCTION OF TRANSFORMER The transformer is very simple and durable in construction and consists of magnetic circuit linking with two winding known as primary and secondary winding. The following are the main components of the transformer as shown in figure. Core Transformer core is constructed from thin sheet of high grade Silicon with 4% of silicon. The sheets are laminated and they are coated with an oxide layer to reduce the iron losses. The purpose of the core is provide a magneti
