9400200990 Rev I DGC-2020 General Information 1-7
Power Factor
Metering Range: 0.2 leading to 0.2 lagging
Calculation Method: PF = P (3-phase average) ÷ S (3-phase average)
Accuracy: ±0.02 ∗
∗ Applies when temperature is between -40°C to +70°C.
Real Power
Indicates total kW and individual line kW (4-wire, line-to-neutral or 3-wire line-to-line)
Measurement/Calculation Methods
Total: PF × Total kVA
4-Wire, Line-to-Neutral: kW calculated with respect to neutral
3-Wire, Line-to-Line: A-phase kW = V
AB
× I
A
× PF ÷ 1000 ÷ √3
B-phase kW = V
BC
× I
B
× PF ÷ 1000 ÷ √3
C-phase kW = V
CA
× I
C
× PF ÷ 1000 ÷ √3
Accuracy: ±3% of the full-scale indication or ±2 kW ∗†
∗ kW metering indicates 0 kW when the generator kW is below 2% of the full-scale rating.
† Applies when temperature is between -40°C to +70°C.
Oil Pressure
