Explanation of Power Factor Values
Energy Results
The power monitor calculates energy values including kWh forward,
reverse and net; kVAh; kVARh forward, reverse and net; and kAh. You
may read these values by using the display module or via
communication.
Phase 1 True Power Factor The ratio between the power and apparent
power for an individual phase or all three
phases; signed to show lead (+) or lag (-). -100…100 Percent
Phase 2 True Power Factor
Phase 3 True Power Factor
Total True Power Factor
Phase 1 Distortion Power Factor 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. 0…100 Percent
Phase 2 Distortion Power Factor
Phase 3 Distortion Power Factor
Total Distortion Power Factor
Phase 1 Displacement Power Factor 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 (-). -100…100 Percent
Phase 2 Displacement Power Factor
Phase 3 Displacement Power Factor
Total Displacement Power Factor
