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?

    It’s over twenty years since I did three phase theory, so feel free to add a few sketches and notes to jog my memory, as I’m not getting a picture in my head of where the neutral current is supposed to cancel in this installation.
