The best information on surges and surge protection I have seen is form
the IEEE:http://omegaps.com/Lightning%20Guide...ion_May051.pdf
And also the NIST:http://www.nist.gov/public_affairs/p.../surgesfnl.pdf
Finally the industry promoter has arrived to 'cut and paste' half
truths. From those citations are reality that Bud refuses to
acknowledge. He cannot. Profits are just too high.
Page 42 Figure 8 of his first citation shows a protector too far
from earth ground. Protector too close to electronics. And a defective
earthing system. Therefore 8000 volts finds earth ground
destructively through adjacent TVs. Bud claims that earthing is not
necessary. it is necessary to sell protectors at gross profit. But
Page 42 figure 8 shows, a protector without proper earthing can even
destroy the TV. A protector too close to TV earths a surge 8000 volts
destructively through that TV. It was not a 'whole house' protector.
Therefore it was too far from earth ground.
A surge finds earth ground. If not earthed before entering a
building, then a surge may even find destructive paths through
disconnected appliances. This was demonstrated even by early 20th
Century Ham radio operators who would put their antenna wires even
inside a mason jar. Damage to disconnected equipment still resulted.
When the antenna (incoming) wire was earthed. then damage stopped.
Protection means surges must be earthed before entering a building.
Bud repeately insists that earthing is not required for protection.
But his second citation says otherwise. From page 6 (Adobe page 8 of
24) of
http://www.nist.gov/public_affairs/p.../surgesfnl.pdf
You cannot really suppress a surge altogether, nor
"arrest" it. What these protective devices do is
neither suppress nor arrest a surge, but simply
divert it to ground, where it can do no harm.
All appliances contain internal protection. Protection that may be
overwhelmed if surges are not properly earthed before entering the
building. Protection that may be overwhelmed if a protector is too
close to an appliance and therefore earths that surge destructively
through the appliance: Page 42 Figure 8.
A long list of responsible companies do make 'whole house'
protectors that costs tens of times less money per appliance AND
provide superior protection. This long list includes names that any
electrically informed guy will recognize: Square D, Cutler-Hammer,
Intermatic, Leviton, GE, Siemens. One 'whole house' protector does so
much more because, well, notice it has the essential earthing wire.
These products are available in Lowes, Home Depot, and electrical
supply houses. Some are avialable for less than $50.
Why do plug-in promoters fear you learn what is necessary for
effective protection? Let's see. Bud's protector is a $3 power strip
with some $0.10 components. It is sold for $25 or $100. With profit
margins that high, then it was essential for Bud to not discuss
earthing. No earth ground means no effective protection.
Meanwhile, Bud will do anything to avoid discussing single point
earth ground. Surge protection is secondary to profit margins. Even
his own citations define earthing as necessary. He ignores that
reality. Bud ignores earthing since products he promotes have no
earthing. Earth ground - not a protector - is the protection. A
protector simply connects a surge to protection. But a protector
promoted as a magic box becomes a profit center.
