High 3rd harmonic on the neutral

MS01
Afternoon,

I was wondering if anyone has nay experiences of having issues with high 3rd harmonic currents on the neutral on high-rised residential schemes? I appreciate  non-linear single phase loads will impact the 3rd harmonic and even on a balanced system harmonics are an issue but we are measuring it at 300% but I can’t think why this may be the case on a residential building.

Does anyone have any ideas?

    Andy -  the data sheet says that it measures true RMS, so that is the reading you would get, the RMS value, i.e. the heating effect value of the waveform present.


    If you use the low pass filter, you will get the RMS value of the 50Hz component.
