Basler Electric DGC-2020HD - Manual (Page 19)

9469300990 Rev B 9
Power Factor
Metering Range ................................ 0.2 leading to 0.2 lagging
Calculation Method .......................... PF = cosine of the angle between phase AB voltage (Vab) and
phase A current (Ia)
*
Accuracy...........................................
±0.01 †
* In single-phase AC-connected machines, it is the cosine of the angle between phase CA voltage
(Vca) and phase C current (Ic).
† Applies when temperature is between –40
°C to +70°C (–40°F to +158°F).
Note
For the DGC-2020HD to correctly meter power factor, the generator
must be rotating in the same phase sequence as dictated by the
generator phase rotation setting.
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...........................................
±2% 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 (–40°F to +158°F).
Oil Pressure
Metering Range ................................ 0 to 150 psi, 0 to 10.3 bar, or 0 to 1,034 kPa
Accuracy...........................................
±2% of actual indication or ±1 psi, ±0.07 bar, or ±6.9 kPa (subject to
accuracy of sender)
Display Resolution ........................... 1 psi, 0.07 bar, or 6.9 kPa
Coolant Temperature
Metering Range ................................ 32 to 410
°F or 0 to 204°C
Accuracy...........................................
±2% of actual indication or as low as ±2° (subject to accuracy of
sender)
Fuel Level
Metering Range ................................ 0 to 100%
Accuracy...........................................
±2% (subject to accuracy of sender)
Display Resolution ........................... 1.0%
Battery Voltage
Metering Range ................................ 6 to 32 Vdc
Accuracy...........................................
±2% of actual indication or as low as ±0.2 Vdc
Display Resolution ........................... 0.1 Vdc
Engine RPM
Metering Range ................................ 0 to 4,500 rpm
Accuracy
* ......................................... ±2% of actual indication or as low as ±2 rpm
Display Resolution ........................... 2 rpm
* When engine speed is below 2% of full-scale, reported rpm is 0.
