VALUE MEANING

The relative (positive or negative) active power is defined in the quadrant examined, and

therefore it takes the value of the active power in that moment.

The relative (inductive or capacitive, positive or negative) reactive power is defined in the

quadrant examined, and therefore it takes the value of the reactive power in that moment.

The relative (inductive or capacitive, positive or negative) power factor is defined in the

quadrant examined, and therefore it takes the value of the power factor in that moment.

The relative (positive or negative) active power or the relative (inductive or capacitive, positive

or negative) reactive power IS NOT defined in the quadrant examined, and therefore it takes a

zero value.

-1

The relative (inductive or capacitive, positive or negative) power factor IS NOT defined in the

quadrant examined.
