CHAPTER-7 circuit breaker. - IIT Roorkee

367 CHAPTER-7 high voltage circuit breaker Introduction circuit breaker is a mechanical switching device capable of making, carrying and breaking current under normal circuit condition as well as under specified abnormal circuit condition such as short circuit etc. circuit breakers are generally classified according to interrupting medium used to cool and elongate electrical arc permitting interruption. Selection of outdoor circuit breakers for switchyards 12 kV and above (highest system voltage ) as regards types, rating, performance requirements and tests for AC high voltage circuit breakers that are installed in hydro power stations outdoor switchyards after the step up transformer on outgoing transmission line f

Special requirement for rating of AC high voltage generator circuit breakers between the generator and transformer terminals are also discussed. 7.1.1 Standards Relevant National and important international standard in this connection are as follows: 1. IS: 13118/ - Specification for high-voltage alternating current circuit
