The minimum requirement for
test tools used in PQ trouble-
shooting are:
•
True-rms for accurate mea-
surement with harmonics
and distorted waveforms.
•
CAT III-600V or higher
(CAT III-1000V) safety rating,
which are appropriate for
measurements on power
circuits
A word on test tools
In addition, instruments with
recording capability, waveform
display and specialized mea-
surements (such as harmonics,
sags and swells, transient cap-
ture, high frequency noise, etc.)
are needed.
The following Fluke test tools are referred to in this application note.
