Excitation power is derived from a three-phase permanent magnet generator (PMG), to isolate the AVR control circuits from the effects of non-linear loads The AVR maintains the constant voltage up to certain level of the load current which is independent of the generator speed and load. A frequency measuring circuit continually monitors the generator output frequency and provides under-speed protection of the excitation system. This is done by generators or parallel operation with the mains with cosO or. KVAR regulation. 2) DESCRIPTION. - The AVR model R610 is composed of electronic cards which. When the Green LED light is "ON", it indicates Power ON and also that the input voltage and output voltage is normal, the regulator is working. AVR. AVR. B.Self Excited Automatic Voltage Regulator Residual voltage at AVR terminal > 5 VAC. Thermal Drift The generator output voltage should build up to a. The SS300 voltage regulator is an encapsulated electronic voltage regulator which controls the output of a brushless AC generator by regulating the.
