Generator circuit breakers(GCB) role in gas turbine power ...· When a gas-turbine generator is started-up, its rotor must be accelerated by external means to about 60% of the rated speed before the start-up process becomes self-sustaining,in other word before the turbine can generate sufficient power to continue process independently. The energy required for this purpose can be provided for instance by a static frequency …
