Description
The ratio between the magnitude of the
fundamental and the sum of the magnitudes for
all of the current harmonics for an individual
phase or all three phases.
The cosine of the phase angle between the
fundamental voltage and current for an
individual phase or all three phases; signed to
show lead (+) or lag (-).
