Generator circuit breakers(GCB) role in gas turbine power plants

Apr 06, 2019 · Generator circuit breakers (GCB) role in gas turbine power plants. 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 converter (SFC).Get price

Circuit breaker - Wikipedia

A circuit breaker is an automatically operated electrical switch designed to protect an electrical circuit from damage caused by excess current from an overload or short circuit. Its basic function is to interrupt current flow after a fault is detected. Unlike a fuse, which operates once and then must be replaced, a circuit breaker can be reset to resume normal operation. Circuit breakers are made in varying sizes, from small devices that protect low-current circuits or individual household applGet price

Switchgear - Wikipedia

In an electric power system, switchgear is composed of electrical disconnect switches, fuses or circuit breakers used to control, protect and isolate electrical equipment. Switchgear is used both to de-energize equipment to allow work to be done and to clear faults downstream. This type of equipment is directly linked to the reliability of the electricity supply. The earliest central power stations used simple open knife switches, mounted on insulating panels of marble or asbestos. Power levelsGet price
