Switchgear

For the auxiliary and protection system for the plant, they need supplies to be in 6.6kV/AC, 415V/AC, 220V/DC, 24V/DC and 220V/AC. All this supply will come from the generation of the plant it’s own. Therefore it needs the switchgear system to arrange and distribute all the supply to the devices accordingly.

This switchgear system also connected to the black start diesel and emergency diesel generators. These two generators are used when there are emergencies like system trip or suddenly lost of supply. During these situations, the emergency generator will automatically cut in and supply 415V to the 415V feeder bus, and the operator will need to manually switch on the black start diesel generator manually to supply 6.6kV to the feeder.
