Harmonic Phase Angles
The harmonic voltage phase angle and harmonic current phase
angle are the standard for the PLL source phase (for input based
on PLL when U1 is selected on this device) fundamental wave
component.
The differences in phase of each harmonic order component and
the phase of the fundamental wave component is expressed as an
angle (°) and - indicates a LAG, whereas + indicates a LEAD.
The phase angle of harmonic power is expressed by the power
factor of each order of harmonic converted into an angle (°). When
the harmonic-power phase angle is between -90° and +90° , the
order of harmonic is flowing in toward the load (inflow). When the
phase angle is between +90° and +180° or between -180° and -
90°, that order of harmonic is flowing out from the load (outflow).
The arithmetic expressions for the harmonic-power phase angle
vary depending on whether the reactive-power-meter method is
ON or OFF.
