ELECTRICALCHARACTER
EXCITATION SYSTEM
AVR：SX440，SX460，MX321，MX341
The main stator supplies power to the exciter stator via the AVR.
The efficiency semi-conductors of the AVR ensure building-up voltage by low residual magnetism of the magnet steel.The exciter rotor output is provided to the main rotor by a three-phase full wave bridge rectifier.
This rectifier is protected by a surge suppressor against surges ecused by short circuit or lost synchronization.Voltage regulation of SX440 AVR with three-phase induction detecting module<±0.5%. MX321 and MX341 suitable for the generator with permanent magnetic generator(PMG).
