AVR Operating Mode

Adjustment Range:

See Generator Voltage Sensing

Voltage Regulation:

±0.25% over load range at rated power factor and constant generator
frequency.

±0.5% with 3-phase sensing and shunt power at 40% THD of the voltage
waveform (due to a six SCR load).

Temperature Drift:

±0.5% for a 40

°C change

V/Hz Characteristic:

Slope from 0 to 3PU is adjustable in 0.01PU increments. Transition
(Corner) frequency is adjustable from 40 to 65 Hz. See Figure 1-2 for the
V/Hz curves.

Response Time:

Within 1 cycle
