Harmonic Analysis

CH1

AH03 = 4 . 725 A - 188 . 4°
> VH03 = 289 . 6mV - 252 . 2°

A thd = 89 . 09 %
V thd = 1 . 170 %

Freq = 61 . 03 Hz
PF = 0 . 746

The PM3300 provides comprehensive harmonic analysis capability.
It will measure the harmonic content of the voltage, current and real power on each
phase, for all components up to the 99th harmonic. Power harmonics are available
via the internal printer.

The Harmonic Barchart display mode provides a convenient way of viewing the
spectrum of distortion components (see page 5).

Analysis of neutral currents and DC components in the waveforms can also be
performed.

Magnitude of harmonic as absolute Phase angle of harmonic referenced
value or % of fundamental to voltage on CH1

HARM HARMONICS

THD This key provides a display menu to select VOLTAGE or CURRENT
FREQ Harmonic and the Harmonic number to be displayed. The harmonics
FUND can then be scrolled through using the ENTER key. Harmonics can be
output to the printer or PC.

TOTAL HARMONIC DISTORTION

This key provides display menu to select VOLTAGE or CURRENT
total harmonic distortion.

FREQUENCY

Displays the frequency of the AC supply. This is the fundamental
frequency for harmonic analysis.

FUNDAMENTAL

Displays the fundamental component of all relevant displayed
measurement functions (see example page 5).
