PPT-Lecture on Transformer By D. M. Parshuramkar

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 . Oils which meet the same specification and class type are miscible in all proportions However when oils mixed as per the above guidelines the mixture should meet the respective standard used In case of mixing unused oils of different origin class PRESENTED BY.

In conventions on Load Transformer Tap Changer there is production of Arc when changing the tapping of Transformer. And in large KVA rating of Transformer it is hard to quench the Arc. This major problem can solve in this thyristor based transformer tap changer.. IEEE Rural Electric Power Conference. April 21, 2015.

Digital Current-transformer Testers (EZCT-10). 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. 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 .
