Harry .. things have moved in since you looked after your boilers.

The mains these days has some rather "unpleasant" loading on it
usually
by semiconductor devices not transformers near saturation. Why is it
that I can clearly see these even late at night when the loading on
substation transformers goes right down?.

Answer me that one if you will..

The electrical load controlled by electronic devices is trivial
compared
with total load.



Then why do they cause waveform distortion and why does the mains get
distorted?..

Even with very light transformer loading's?..

it's not them that does it.



So -what- does it then ?..

Be a bit more specific please...

Sigh
As I said earlier

I further note from the above that it can result from defective/useless
digitalised equipment and so be entirely spurious.
Ie not exist at all.
A lot of digitalised instrumentation is useless. It only approximates.
So the pix someone posted may well be spurious too.
Unless he has a "proper" analogue oscilloscope, not driven outside it's
limit.
The most likely explanation come to think.




Harry like most everything else you think you understand you have this
wrong .. totally wrong ..

A few words .. please rearrange...
