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.

Based in Australia, Electrical Courses Perth is the top electrical training institute for studying the nationally accredited electrical training courses. We offer nationally-recognised, government-funded Electrical courses, EEHA courses, Electrical Instrumentation courses, etc. in Perth. Tunnel Boring Machine(TBM) Most of the parts work with use of electrical motors and . consumes electrical power, generating electrical power on site with use of generators and connection also with government supply, this supply(11KV) reach to TBM after synchronization of generators with use of power cables and junction boxes, Step down this power with use of Transformer(11KV/690-400V) and Consuming this power for operation of TBM.. 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. 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.
