I discovered relating to this result in a manufacturing facility where by we generally employed pure sine wave variable frequency motor controllers on very long cables simply because excessive distortion on a protracted cable could melt away up a motor. All the outlet property UPS I have witnessed seem like pure sine wave.
That UPS's output quality isn't base on the barrel. Are you presently sitting down? Here's a small-finish UPS from your exact same company that built all 3 from the UPSes earlier mentioned:
This can be ample distortion to indicate up while in the oscillogram about the remaining: notice the fairly flattened peaks.

Melted a dip into the UPS situation and had been over and over brighter right before burning up. I believe it was using a capacitor to provide a set resistance at sixty Hz though the UPS harmonics caused significantly less obvious resistance so an excessive amount of power handed in the capacitor.
