connected to same AC line. The circuit even involves things sometimes
considered non-conductive; that are conductive to surges.
Let's make this clear but again. To make your assumptions valid,
then explain why all those devices not on surge protectors were not
damaged. IOW you have no idea what was and was not protected by
plug-in protectors.
Let's make this clear but again - VCR and TV connected to same AC
wall receptacle. Neither on a surge protector. One damaged. The
other not. Why? Is one connected to the invisible surge protector?
No. Leythos makes assumptions as to how surges damage electronics.
His speculations cannot explain why only one of two appliances in same
wall receptacle are damaged because his assumptions ignore the most
critical component in surge protection: earthing.
Let's make this clear but again. Where do those protectors even
claim to provide protection for each type of surge. Where are the
numbers? Why are various surges not listed in numerical specs?
Because one would learn a protector designed for one type of surge does
not protect from a typically destructive surge. Plug-in protectors
manufacture hope you will assume as you have done ... and forget about
so many other undamaged devices apparently on 'invisible' protectors.
Leythos cannot explain why so many other unprotected devices were not
damaged because he ignores the complete circuit and ignored the most
critical protection component - earthing. It's called learning
details before assuming blanket conclusions.
IEEE Standards make it obvious. Protection is about earthing. Those
plug-in protectors have no earthing connections that routine in
effective protectors. No earth ground means no effective protection -
as was well understood even 70+ years ago.
70 years ago, they also did not use invisible protectors. 70 years
ago, Ham radio operators eliminated damage by earthing incoming antenna
wires. Same principle well proven that long ago.
Your examples tell us nothing useful because other relevant circuit
components (wires inside walls, location of earth ground electrodes,
incoming utility wires, what was the incoming and outgoing surge path,
etc) have not been provided. Therefore we can only speculate. What
do we know from well proven papers even from 1930s Westinghouse and GE?
Protection is about earthing. Protectors without that essential earth
ground connection are not effective. Without a protection 'system',
then protection even inside a DSL modem may be overwhelmed.
Leythos concludes only from observations, without first learning the
surge circuits, and by denying well proven engineering principles about
earthing. This is how junk science is also promoted. No earth ground
means no effective protection. No way around that well established
fact - as even stated in IEEE standards and routinely demonstrated in
virtually every town every year.
