Different power factor displays at the unit:
i0.91 (inductive)
lg.91 (lagging)
c0.93 (capacitive)
ld.93 (leading)
Reactive power display at the unit:
70 kvar (positive)
-60 kvar (negative)
Output at the interface:
+ (positive)
- (negative)
In relation to the voltage, the current is
lagging
leading
The generator is
over excited
under excited
Control: If the control unit is equipped with a power factor controller while in parallel with the utility:
A voltage lower "-" signal is output as long as the
measured value is "more inductive" than the reference
setpoint
Example: measured = i0.91; setpoint = i0.95
A voltage raise "+" signal is output as long as the
measured value is "more capacitive" than the refer-
ence setpoint
Example: measured = c0.91; setpoint = c0.95
