Regulation
The following modes are used to regulate the CGCM-DLR unit.
AVR Operating Mode
• Accuracy: ±0.25% over the load range at rated power factor and constant
generator frequency.
• Steady State Stability: ±0.1% at constant load and generator frequency.
• Temperature Drift: The maximum error due to temperature drift is
0.005% of full scale per degrees Celsius for voltage and current
measurements and 0.010% of full scale per degree Celsius for watt and
VAR measurements.
• V/Hz Characteristic: Slope from 0 to 3PU is adjustable in 0.1PU
increments. Two knees and two slopes are available.
• Response Time: < 1 cycle.
FCR Operating Mode
• Accuracy: ±1% of rated current.
VAR Operating Mode
• Accuracy: ±0.4% of the nominal VA rating at the rated frequency.
Power Factor Mode
• Accuracy: ±0.02% of the PF setpoint for the real power between
10...100% at the rated frequency.
