Line Harmonic Analysis
Line Power Analysis easily measures a power conversion device’s incoming RMS line voltage, RMS current
consumption (in watts and VA), Power Factor, Apparent Power, and Real Power. Line current harmonic
measurements are made and compared to standard templates for EN 61000-3-2 Class A, B,
C, or D equipment. Results can be displayed in either graphical frequency
domain or tabular formats.

Line
current harmonics are viewed in graphical and tabular format
simultaneously. The proper template for the selected class and
line frequency is calculated and displayed. As each current
waveform is acquired, each harmonic’s value is displayed on
the graph. You can use a cursor to select individual harmonics
for measurement purposes. Out-of-limit harmonics are shown
extending beyond the template. Tabular harmonic data for each
frequency is displayed along with its frequency and magnitude
limit. Harmonics exceeding their limits are also indicated in
the table.
