Page 12: Generator Control Panel
INFORMATION 2.4.2 Generator control panel Technical Information 2.5.1 AC alternator The tri phase synchronous alternator is directly coupled, one bearing, brushless, rotating field design, 12 wire, four pole (1500 RPM) and regulated by an Automatic Voltage Regulator (AVR). The exciter stator has a residual magnetism, which guarantees self-exciting of the generator on start-up (that thereby generates a residual voltage of about 10% nominal voltage). - Page 13 INFORMATION Further technical data on the design of the alternator can be found in drawings and diagrams in this manual. Fig. 11: Automatic Voltage Regulator (AVR) Fig. 12: AVR Trimmers (potentiometers) The power comes from 12 wires that can be connected in star, delta or combined double / star and double / delta arrangements to take off different voltages.
