The modern digital technology has modified the requirements for instrument transformers used for measurement and protection applications.The modern secondary equipment does not need the high power out The performance of a transformer can be calculated on the basis of equivalent . circuit.The. . four main parameters of equivalent circuit are: . - . R. 01. as referred to primary (or secondary R. 02. Introduction. Transformer . is the main reason to transmit and distribute power in AC. Transformer is a device which works on the principle of mutual induction. . Principle. . of operation. It is based on principle of . In electrical power system the range of current and voltage is very high and so it is not possible to measure these values directly by any meter of reasonable size and construction.. So there is a need to step down these voltages or currents to such a value so that it can be easily measured.. The transformer is a static device which is used to transfer electrical energy from one ac circuit to another ac circuit. . Input to a transformer and output from a transformer both are alternating quantities (AC).. El-Sharkawi@University of Washington. 2. Why do we need transformers?. Increase voltage of generator’s output. Transmit high power at low current. Reduce cost of transmission system. Adjust voltage to a usable level. PREPARED BY:. VRUNDA RANA (131130107049). KRIMA .
