The droop adjustment is normally preset in the works to give 5 voltage droop at full load zero power factors. Mx automatic voltage regulator avr specification controls and accessories voltage.
Newage Stamford Generator Manual Avr Stamford Macfarlane
Avr mx321 wiring diagram. Stamford as540 automatic voltage regulator. A043y701 issue 2 5 ref. Is connected to s1 s2 on the avr see generator wiring diagram for details. Red capacitor generator circuit diagram avr mx mx is a three phase sensed automatic voltage regulator and forms part of the excitation system for a brush less generator. 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 and to reduce radio frequency interference on the generator terminals. Refer to wiring diagram before removing the shorting link and connecting the droop transformer.
The avr responds to a voltage sensing signal derived from the main stator winding. S1 s2 on the avr see generator wiring diagram for details. Refer to alternator wiring diagram for connection details. The droop transformer must be connected in the correct main output terminal for proper operation details are as shown in the machine wiring diagram. The droop adjustment is normally preset in the works to give 5 voltage droop at full load zero power factor. The main stator provides power for excitation of the exciter field via the sx460 sx440 or sx421 avr which is the controlling device governing the level of excitation provided to the exciter field.
