Power surge suppressor ?

Well at least its not an audiophile cable by Russ Andrews. I've no doubt his
would set you back a mortgage on your house.

I was going to ask if Monster were now making power surge protectors when
I though I'd better Google first, and up popped
http://www.monstercable.com/power/Monster_Power.asp.

Why am I not surprised? :-)))

Ah, well obviously not selling many five year warranties these days then.
I've not heard that this town is particularly bad for lightening strikes.
Now if you had been in Wales, I could understand it a bit more.

IMO *ALL* modern equipment is oversensitive to spikes. There's only
so much that a suppressor or some such can do. I suspect that the
bog-standard protected 4-ways from the likes of B&Q are likely to be
cheaper and just as effective but if you really have got a source of
spikes in your home, for example faulty switches or an aging
central-heating thermostat, you should get it fixed. That's the best
protection of all.


Can't say that I've noticed this. There might be RF interference, but I
can't remember any mains-borne causing trouble. Maybe I've just been lucky,
but then again I don't tend to operate the shredder when the PC in on as
they share the same power socket!

I'd not say anything is worse than anything else in thesurgestakes, but
for most purposes I still feel one of those little wire in the plug devices
would suffice. Nothing will protect you from the really big one from a
lightening strike etc in any case.

Those plug-in devices do not even claim to protect from anything
destructive. View the numeric specs. No numbers for protection from
each type of surge. They are not selling protectors. They are
promoting a massive profit margin. A scam that people such as Mike
Tomlinson approve of and will post personal attacks to defend.

BT routinely suffers even direct lightning strikes with no
electronics damage. The technology is well proven. And not found in
scams sold in plug-in protectors - ie Monster Cable. A BT Central
Office (CO) may suffer about 100 surges with each thunderstorm. When
was your town without phone service for four days while they replaced
that computer?

Key to surge protection is not a protector. The NIST (US government
research agency) says what the effective protector must do:
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.

But a protector without that less than 3 meter connection to earth
will not provide protection. See spec numbers from Monster Cable
which are typical for plug-in protectors. Protection is always about
where energy dissipates. Either energy is harmless absorbed in earth
- does no damage. Or energy is inside the building hunting for earth
destructively via appliances. The Monster Cable even provides more
potentially destructive paths for that surge through appliances.

A surge current not inside the building is not causing damage. That
is why BT suffers direct lightning strikes and no damage. That is
what any responsible homeowner does to have any surges - including
direct lightning strikes - and no damage.

The typical lightning strike is 20,000 amps. Therefore one 'whole
house' protector connected short to earth is rated 50,000 amps or
better. Keison is one source. Only one protector is needed for
everything. That means every appliance is protected for about £1 per
appliance. Or spend £100 per appliance for the Monster. Everything
must be protected or everything - including that Monster protected TV
- is at risk.

All appliance contain significant protection. Makes no difference
what the screen technology is. But a rare and destructive surge
typically occurs once every seven years. A surge that can overwhelm
protection inside all appliances is the only reason for surge
protection. Responsible homeowners earth one 'whole house' protector
so that energy does not seek earth destructively via appliances. So
that the surge does not overwhelm protection inside appliances.

But again, the protector is not protection. You must do what BT
does. You must connect that protector short (ie 'less than 3 meters')
to a single point earth ground. Same ground must be used by AC
electric, telephone, satellite dish, and cable wire. Otherwise
destructive surge energy will enter the building.

Surge protection is always about where energy is dissipated.
Always. Therefore a protector is only as effective as its earth
ground. Monster (and other scam protectors) have no earth ground. Do
not claim effective protection. Its few hundred joules cannot absorb
surges that are hundred of thousands of joules. So it selling a scam
AND does not even claim to protect from destructive surges. Monster
Cable and other plug-in protector are obscenely profitable - not
effective surge protection.

NIST describes Monster and other plug-in protectors:
A very important point to keep in mind is that your surge protector
will work by diverting the surges to ground. The best surge
protection in the world can be useless if grounding is not done
properly.
Monster Cable and other ineffective protectors have no less than 3
meter connection to earth AND do no even claim that protection in
numeric specs. A protector is only as effective as its earth ground
– which is why even direct lightning strikes cause no explosions in
munitions dumps and why BBC radio and TV equipment suffer direct
strikes without damage. The technology is what well proven and that
well understood for over 100 years. A still some will reply with
insults rather than learn how protection from all surges is routine.

Actually, there have been a number of well documented cases where severe
damage to TV transmitters has occured.

Tell me about it!
I used to (seemingly) spend half my life in mid Wales replacing masthead
amplifiers and PSUs after nearby lightning strikes (and at least one fitted
to a field mounted aerial eaten by cattle.)

But it really was predictable, wasn't it? He has a Google Alert set to

Sounds as if people have stopped buying extended warranties.

The sort of thing you can get from Maplin for a tenner in any case.

Got a nice Surgeguard power protector built into a 6 way strip
in the last Sainsburys sales for 6quid.
