GFD233A 3BHE022294R0101 Static excitation
This system eliminates the exciter and uses a transformer as the AC excitation power source. The excitation transformer is connected to the generator outlet or the plant busbar.
It consists of an excitation transformer, an excitation control unit, a thyristor bridge rectifier, a magnetic field switch and an excitation starting device.
This system has a fast response time and its power supply is connected from the generator side and the brushes are used to provide the excitation current. The DC voltage is obtained by rectifying the thyristor bridge circuit. During the start-up process, the starting excitation field is supplied from an external power source
