The Electric transformer is an optimum device which is used to raise as well as lower the currents and voltages in an electrical circuit. This is highly needed for a modern electrical distribution system and assists in boosting the voltage levels. Its utilization can decrease the line losses during the process of transmission. The advantages of Electric transformer includes less cost, reduced weight, compact size and minimal assembling requirement. Less space use, delivery of power, higher efficiency, simple installation etc. It allows for simple transportation and elementary installation.
