Stamford sx440 avr automatic voltage regulator generator avr 3 phase avr for generator:

Generator AVR SX440 is for Stamford brushless ,50-500KW ,1/3 phase Generator ,universal  in 50/60HZ

Specifications:

The SX440 AVR positive voltage build up from residual levels is ensured by the use of efficient semiconductors in the power circuitry of the AVR. The AVR is linked with the main stator windings and the exciter field windings to provide closed loop control of the output voltage with load regulation of +/- 1.0%.

In addition to being powered from the main stator, the AVR also derives a sample voltage from the output windings for voltage control purposes. In response to this sample voltage, the AVR controls the power fed to the exciter field, and hence the main field, to maintain the machine output voltage within the specified limits, compensating for load, speed, temperature and power
factor of the generator.
