How To Use A Harmonics Test In A Fluke 435 Power Quality Analyzer


In this video, we’re going to cover how
to use the harmonics test on the Fluke 435. We start by activating our menu and then selecting harmonics with my arrow keys. Confirm that by hitting the enter
button and we prepare the SD card for the test. Most harmonics are going to show up in
amperage. So I’ll use the F1 button to toggle the amps and generate some
harmonics. In this case, we can see that the third is the most prevalent, followed
by the fifth and the seventh; indicative of a single-phase power supply. If I
switch my function on the demo board, we have more fifth now, which is indicative of a three-phase power supply. To see these signals, I can hit the scope button, I’ll toggle over to the scope, I can switch to amperage and over to a
phase. So I can see phase “A”, my voltage being the larger sine wave, and my
current waveform being the double hump that shows a three-phase power supply. If
I switch back to the single phase, which you’ll see is a single hump. Let’s go back to my harmonics screen. Again, we see the current waveforms, the third and the fifth being the most prevalent right
now. I can switch to “Meter” and see a meter view. There’s lots of data in
harmonics. The arrow keys will scroll down through this all the way down to
the 51st harmonic, both voltage and current. I can also look at a trend by
hitting the “F3” button. This will show a strip chart-type recording. Beyond that…
one thing to note is that my events counter is always active, no matter what
test were using on the Fluke 435. If I hit the events key and come to see
normal, you’ll see I had a few dips and swells occur during the test. So even
during harmonics testing, I see other types of voltage events. That
concludes how we use the harmonics test on the fluke 435.
