• This is the total kilovolt-amperes drawn by the load, as calculated by the product of the load-voltage primary kV (FC 10) times the
primary load current (FC 9). See Figure 5-3.

• This is the total kilowatts (true power) consumed by the load.
• This is calculated by the product of the power factor (FC 13) times the kVA load (FC 14). See Figure 5-3.
• During reverse power operation, the control requires source voltage from a differential or source potential transformer or from
the source voltage calculation (see FC 39) to obtain this parameter. Lack of this voltage will result in the parameter displaying
dashes.
16 Metering Instantaneous 016 kvar Load
XXXX.X kvar
0 NA NA NA NA NA
• This is the total kilovolt-amperes reactive (reactive power) drawn by the load. The reactive power adds to losses on the line, yet
does not do any work. See Figure 5-3.
• During reverse power operation, the control requires source voltage from a differential or source potential transformer or from
the source voltage calculation (see FC 39) to obtain this parameter. Lack of this voltage will result in the parameter displaying
dashes.
17 Metering Instantaneous 017 Line Frequency
XX.XX Hz
0 NA NA NA NA NA
• This is the frequency of the power line, as measured by the control.
• The control is capable of operating on systems from 45 to 65 Hz with no loss of accuracy in its measurements.
18 Metering Instantaneous 018 Voltage THD
XX.X %
0 NA NA NA NA NA
• The total harmonic distortion (THD) is displayed after entering FC 18.
• The total harmonic distortion is computed as the RSS (square root of the sum of the squares) of the individual harmonic
values.
• This is displayed as a percentage of the fundamental RMS voltage.
• Example: 120.0 V of 60 Hz fundamental (power line frequency), with a reading of 0.5 at the 7th harmonic (420 Hz), is 0.6 V
RMS.
