Harmonics

Harmonics display the amplitude and phase of each harmonic to the

63rd harmonic in both graphical and textual format. User can select

which parameter to show the harmonics for (V,I,W), which channel

(A,B,C,D), zoom in a the 5Hz components, set options such as showing

harmonics and/or interharmonics and displaying in Hz or harmonic

number, scaling to the fundamental or absolute value, and a list of the

harmonic magnitudes and phase angles in tabular fashion.

Phasor diagram

The phasor screen displays a graph that indicates phase relations

between voltage and current based upon the angles at the fundamental

frequency, as determined by Fourier analysis. Phasor diagram displays

voltage and current phasors for all channels. Functioning as a phase

angle meter, the unit can display system imbalance conditions and

provides such information in textual form also. The phase angle display

can also verify if monitoring connections have been made correctly.

Animated phasor demo rotations demonstrating resistive, inductive and

capacitive loads can be displayed.
