Generator Avr as480 stamford generator parts Generator Parts Technical data The AS480 is a half-wave phase-controlled AVR which forms part of the excitation structure of the brushless generator. Which also incorporates  an interface to the optional excitation boost system(EBS) for the use where short-circuit current safeguarding is required.  Positive voltage build up from residual levels is ensured by the use of proficient semiconductors in the power circuitry  of the AVR. The control and voltage sensing circuits have separate terminals, allowing the excitation power to be resulting directly from the stator winding for necessary applications or from an auxiliary  winding if sustained short circuit performance is essential. Which is linked with the main stator windings and the exciter  field windings to offer closed loop control of the output voltage with load regulations of +/- 1.0%, In response to his sample voltage, the AVR controls the power fed to the exciter field, and hence the main  field, to sustain the machine output voltage within the specified limits, compensating for load, speed, temperature  and power factor of the generator.
