SR 4 GENERATORSYSTEMS OPERATIONOUTPUT VOLTAGE SENSINGVoltage sensing by regulator module (A1) is througha circuit from connections in phases 1 and 3 of stator(L6) to terminals (20) and (22). The circuit then goes:From terminals (20) and (22) through wires (20) and(22) to spade terminals (1) and (2) on regulatormodule (A1).Through regulator module (A1) to spade terminal(5).From spade terminal (5) on regulator module (A1)through wire (5) through the red wire to voltagedroop rheostat (R1).From voltage droop rheostat (R1) to voltage levelrheostat (R2).From voltage level rheostat (R2) through wire (6) tofuse (F1).Through fuse (F1 ), thermal protector (TP) and wire(24) to terminal (24).From terminal (24) to the tapped connection inphase 2 of stator (L6).The voltage divider in regulator module (A1) has acapacitive reactance. Since capacitive reactance will goup as frequency goes down or will go down as frequencygoes up. the regulator module gives a voltage control onthe basis of volts per hertz.L6 StatorA1Regulator moduleF1 FuseR1 Voltage droop potentiometerR2 Voltage level rheostatTP Thermal protector34
