چکیده:

Within the scope of this paper the two schemu "without" and "with" gene- circuit-breaken axe compared. It is 6hown that the application of the generator circuit-breaker: * tesults in an improved, 6impleA and cheaper layout of the power plant with easier commissioning and operation, cleaner responsability and competence and thus less susceptibility to human and sy,6tem errors
* teplaces elements with ,relatively high fsilure tate,6 by one very teii able element with very low failute tate,
* teduces the 6;tte,6.su on components in normal operation, thus avoiding eventual breakdown and increasing Their lifetime and
* teducu dramatically the extent of damages in case of direct ox indirect aults thus minimizing tepaiA coast and outage times.
However it must be noted that also the generator circuit-breaker cannot .spirit away inherents faults, but it can achieve that possibly they do not have a negative effect. In another paper the two scheme,6 ate compared with respect to availability, economy and operation.
