This analyzer shows all harmonics up to 31. So its 50, 100, 150, 200 Hz roughly up to 2khz. More professional fluke analyzers shows up to 55 harmonics, but it still not mhz range.F1zus wrote: β27 Jan 2023, 18:16No, such an analyzer will not suit us.
You need an analyzer that shows frequencies from 50Hz to 1MHz.
To combat harmonics are suitable:
1) online ups
2) inverter voltage stabilizers
3) isolating transformers
4) network filters.
Online ups and inverter regulators perfectly suppress harmonic distortion and have no more than 5% distortion at the output.
I will be testing these devices soon.
Further it from base frequency amplitude is lower, so 31 harmonics is ok.
Online ups is definitely not working, its tested almost by everybody here, just search by forum.
Network filter doesnt work too, I have lowpass filter and its doesnt do anything. However on graph we see that its working in same frequency range, but no effect.
Isolating transfromer is on delivery, few days and will test it.
So probably its not harmonics. Or you need to take measurements in confirmed place without lag and compare it with confirmed place with lag.
