A plug-in (point of connection) protector can even cause damage to
nearby appliances. *It is the first conclusion in that IEEE paper:
Conclusion:
1) Quantitative measurements in the Upside-Down house clearly show objectionable
difference in reference voltages. *These occur even when or perhaps because, surge
protective devices are present at the point of connection of appliances..
* Each layer of protection is defined by the only item that makes
surge energy harmless. *Protection is always about where energy
dissipated. *And why more responsible companies sell the 'whole house'
protector.
Most of those same responsible companies also sell plug-in surge
protectors too. Some recommend using them in conjunction with their
whole house surge protectors. So there goes that arguement. One
would think W would have learned to stop bringing this bogus argument
up since it's so easy to demolish, but here we go again.
*A protector is only as effective as its earth ground. *An
effective protector also costs tens or 100 times less money per
protected appliance.
Still waiting for an explanation of the obvious contradiction here.
W claims that all electronics and appliances have built-in surge
protection and that it works. Now, if surge protection is only
possible with a short direct connection to earth ground, how is that
protection possible? And how is it that the same components, ie MOVs
inside a TV can be effective, yet even larger ones in a plug-in surge
protector next to the TV are ineffective?
How is it that electrical systems on airplanes are protected from
surges? Where is their earth ground?
And if W knows so much about surge protection, where is the link to
that 50KA rated whole house surge protector for less than $50 that he
claimed is available at HD?
