|GENERATOR CIRCUIT - BREAKER FOR THE SECURITY OF BLOCK TRANSFORMER IN POWER WITH 230 MW POWER BLOCKS|
Technical and economic applications of generator circuit breakers exploitated in the power plants equipped with 230 MW power blocks are presented in this paper. The pressure in the transformer boiler is a increasing function of short-circuit duration time. Applying short-circuit breaker mainly thermical effects are limited also the other aspects of short circuits like power disponibility, exploitation period and other effects are discussed. Also some other economic aspects are analyzed. The paper will be illustrated by the characteristics taken from the Polish power plants and abroad.
