•This is the power factor of the primary circuit, as represented by the phase difference
between the line current and voltage.
•Lagging current, or inductive loads, are designated by an implied (+) sign, and leading
current, or capacitive loads, are designated by a (-) sign. Refer to Figures 5-1 and 5-2.

•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 18.

•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 18.
•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.
