Schematics for brick wall

[stefanv]

I've learned the importance of a good ground for surge protection.
According to Brick Wall, they do the best surge protection even without
ground. I'm looking for more info on their system.
Anyone got a schematic of a Brick Wall or similar surge-device I could
study?

Thanks, Stefan V

They may do better than other systems with a missing ground but I very much
doubt they are better than other systems that have a proper ground in place

Great link, thanks!

Does anybody know the different stages in the Brick Wall? Their site gives
some idea, but looking on the net I can't find enough details to really
understand it.

Unless you obtain a Brick Wall unit and strip it down and surmise its
operation, I doubt you will find any meaningful technical data on it.
However, from their web pages I gleaned this piece of info;

Brick Wall surge protector products are based on the current (hence
voltage) limiting of a massive inductor. Residual energy that leaks
through is captured by a series of electrolytic capacitors. There it
is slowly leaked back to the neutral at a harmless level. Outside of
trivial amounts of parasitic capacitance our Series Mode surge
protectors do not put any surge current on the ground of your systems.
Engineers of an MOV based surge protector face the dilemma of what to
do with potentially large amounts of surge current. They don’t want to
overload the neutral and want to prolong the life of the MOV. Using
two MOV's and diverting equally between the ground and neutral wire
prolongs MOV life and prevents overcurrent on the neutral. Series Mode
surge protector technology presents no such dilemma.

Reading the blog on their pages does not fill me with confidence as to
the effectiveness of their apparently "amazing technology".

The manufacturer has put out this documentation (for what it's worth)
http://www.techsavvy.com/industry/file/national/03v0r/pwc05.html?id=98093&comp_id=03V0R&base_region=*

Series mode protectors are simply low pass filters. Some will make
protectors 'sound' as if something more. Text will hype energy storage
devices and other irrelevant concepts such as 'does not work until so
much voltage first occurs'. It's all nice. But then they even
forget to mention a wire that carries destructive transients completely
bypassing the series mode protector.

It's a low pass filter. Nothing magical or miraculous about it.
It's a low pass filter. And what do many electronics already
contain? A low pass filter.

If the technical documents do not define a series mode protector in
terms of filtering, then suspect spin. Series mode protectors perform
as low pass filters. Filters that can supplement a protection system.
Filters that, like protectors already inside electronics, can be
overwhelmed if primary and secondary protection systems are not
functional.

Basically it is more line filter than surge suppressor. I hope that that

they do not have electrolytic capacitors as they are not normally AC
components (They are polarized / have distinct plus and minus terminals
like a battery). They do have a point about not using ground to conduct
surge currents.
