How different is your 60 Hz waveform distortion compared to my plots?
My plots probably imply capacitor input power supply loading that starts before the sine wave peak. Possibly two slightly different starting points for different types of power supplies.
Then some big load occurs just after the peak. This is probably some other type of load. Looks to be close to 120 deg from the zero crossing.
Although I have three phase on the pole I don't have it in the house. Thus, I don't know how the other two phases look here.
Full view of the sine wave:
Enlarged view near the sine wave positive peak:
Both positive and negative peaks are quite similiar.
