High 3rd harmonic on the neutral

MS01 over 4 years ago

Afternoon,

I was wondering if anyone has nay experiences of having issues with high 3^rd harmonic currents on the neutral on high-rised residential schemes? I appreciate non-linear single phase loads will impact the 3^rd 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?

I have found a Diagram that shows the waves in relation to each other showing why you can end up 200% above where you expect to be.
