3.3 Export Watt and Var measurements
The MultiLed displays Export Watt and VAr readings by the
corresponding Export annunciator led illuminating. If export
annunciators are not illuminated Watt and VAr readings are
importing.
3.4 Leading and Lagging Power Factor
( Capacitive and Inductive loads).
3.4.1 Leading Power Factor.
A negative sign in front of the power factor reading
indicates a Leading Power Factor. i.e. The current is leading, the
load is capacitive. Example - .5000 P.F. indicates a Leading
Power Factor of 0.5 (capacitive load).
3.4.2 Lagging Power Factor.
No sign in front of the power factor reading indicates a Lagging
Power Factor. i.e. The current is lagging, the load is inductive.
Example 0.5000 P.F. Lagging Power Factor of 0.5 (inductive
load).
3.4.3 Quadrant indication.
If the Export LED annunciator is illuminated this indicates power
factor is in a negative quadrant. If Export LED annunciator is not
illuminated this indicates the power factor is in a positive
quadrant.
