    People,

    Can anyone please advise if there a product exists that can be connected into a ring circuit to provide surge protection?

    I wish to apply surge protection to the ring to protect computer equipment without using an extention lead and without using surge protected sockets (if such a product exists).

    I would preferably like a product that can be wired in without notifying the council or commissioning an electrician to do the work.

    Many Thanks




    Paul

    Where are the surges ( or more accurately voltage spikes ) coming from ?

    If they are comming from other appliances on the same ring then the only way to stop them is a barrier between ring and the computors and that can only be at the socket in the plug or in a lead.

    If the surges are from other ring or from the incoming mains then an electrician could install a heavy duty filter between the consumer unit and the ring circuit feeding the computors. Expensive and not a DIY job.

    Do you have any specific reason to believe that there are 'surges' you need protection from - and, if so, do you have any idea what is causing them?

    Kind Regards, John.

    guys, thanks for your help. I don't know if there are any surges at all tbh. However, I assume that most people who fit them (as part of an extention lead) do so as protection should surges ever occur. Similarly, I wanted this sort of protection but am not a lover of extention leads

    A massive industry has arisen (and is doing very nicely) selling 'surge protection devices' which address a problem which the vast number of people don't actually have.

    Kind Regards, John.

    As nicely illustrated here

    Again, the electrical con-man has a product for those who continue to be born yesterday.

    How can you call him a con-man when he explains the technology being used? i.e. Quantum Resonant Technology.

    The Quantum Resonant Technology Qx2 and Qx4 are sophisticated Scalar field generators, employing technology derived from research in the discipline of quantum mechanics that allows the ordering and stabilization of magnetic field effects, effects that are significant and widespread within and around high-quality audio and visual systems. Each component passing current will produce and also be affected by the multiple magnetic fields that result, not to mention the powerful permanent magnets employed in loudspeaker drive units. The QRT field generators are an effective, proven method of minimizing the sonic and visual impact of these stray fields. Simply listen to or look at their impact on your high-end audio or AV system to understand just how important their contribution can be. But you don’t need to take this on trust; Quantum Resonant Technology units have produced significant, repeatable and measurable changes in the performance of hi-fi and visual display units under test.

    I'm sure that if quantum electrodynamics were a field known to the popular press, then "QRT" would suddenly become based on it.

    Thanks for that, and thanks for the useful info - until I read that I thought QRT stood for Quack Related Theft.

    How silly of me.

    I'm immediately suspicious of any product using the word 'Quantum'.

    Just as anyone using the word 'workshop', in a context other than light engineering, is a tw@.

    I think that's a bit extreme.

    Even if you're dismayed by the tag being applied to any meeting long on time and short on agenda, there are lots of examples where people could be working in a small-ish room doing things that couldn't really be referred to as "light engineering" but the room would be a workshop.

    OK a computer uses a switch mode power supply. These turn AC to DC and store it in a capacitor then turn it back to AC at high frequency it's then transformed to voltage required and turned back to DC sampled and the mark / space is altered to ensure the correct voltage is sampled at the output capacitor.

    Now explain how any spike gets through that? Especially with laptop power supplies where the input voltage is anywhere between 100 and 250 volt and it feeds into a battery.

    The spikes are far more likely to be caused by a switch mode power supply than the power supply being affected by spikes. I have run both desk top and laptop from a modified sine wave (Really square wave) inverter without a problem if thy can run from those the likely hood of any spikes causing a problem is very low.

    The problem is every filter network has some earth leakage and with all sockets under 20A now being protected by RCD adding extra filters is likely to cause the RCD to trip more often.

    Yes I use filters but not to protect the computer they are to reduce interference on my amateur radio computers are horrors for producing nasties. Yes the computer can be affected but by air born not through the mains. USB keyboards seem to have a problem working with HF flying around. But no amount of mains filters will cure that is just a case of using PS2 keyboard instead.

    Thanks BAS!

    I'll let those hard-disks through under the dispensation that it's merely a brand name.... and I'm also thinking of replacing my bath with one of these: http://www.carronbathrooms.com/Carron Bathrooms - Quantum Family.html fairly soon.

    Quantum healing justifies the suspicion.

    I object to use (2) as noun and as a verb. It's not going to get me anywhere and is futile. Oh well. However, my tw@ometer does register activity in these circumstances:

    "...a group of people engage in intensive discussion and activity on a particular subject..." For some reason, the tw@ishness registers higher when it is 'workshop' and not a 'meeting', 'seminar' or 'discussion'

    "...using intensive group discussion and improvisation..." can achieve full-scale deflection. Sometimes as much as 50 Brandreths.
