What exactly is an Audio Grade Servo Stabilizer?
Vertex people add a better/souped up cable amongst other things to the regular servo stab. some members from bangalore have that version.

Hi Venkus
Your link doesn't work.
Hey Venkus_Narelius, When we click the link, the following web page opens up which is basically blank page.Hey Capt...link is working and it leads to a pdf file...you gotta save it or open with acrobat reader.
There are some essential points which everbody is missing:-
1. Every electrical item has something called a response time.
2. To fry you electronics takes a few milliseconds of high voltage/high current.
Now for the facts:-
Relay operated systems (unless they are using expensive solid state relays) take between 50 -100 milliseconds to act.
MCBs & ELCBs also have a similar time response.
Servo stabilisers can take upto 200 milliseconds before they start acting. Most low cost ones get into the act in about 500milliseconds.
So you use what I call the high voltage rupture discs (electrical engineers amongst you can let me know the exact technical name please!). The almost instantaneously close the line & neutral when voltage rises beyond the set value. This gives time for your MCB/ELCB to kick in. No current passes upstream of the ruptured disc. Have experienced this umpteen no. of times & saved lakhs of rupees in potential damages.
I have not seen any current ratings on these units. But I know that they are available in various voltage ratings.
PnReddy: Yes for 3 phase connection you will have 3 units across each pair of phase & neutral. But this will be only single phase protection individually. If you are using a 3 phase 440 V unit you do not require this. What you will require is a single phasing cut-out.

well i use.. normal spike protectors.. and ups..
and that works..
i had 2 ups lying unused got the battery replaced and both of them have a fuse as well as backed up with a spike protector..
nomal 500va ups gives 20mins back up for tata sky HD and LCD together with medium backlight. (that i have tested )
Just wondering if all surge strips (say from Writex, Quantum, etc) offer the same amount of protection from surge, though only a few offer this warranty scheme. Anyways the ones offering warranty (Belkin Gold series) are at least twice as expensive as the warranty-less ones. Though its a small price to pay for the immense peace of mind. Looking to get one. Thanks for the heads-up Ram.
PS: Does the warranty cover damage from surge due to lightning???
Am I just the cynical one, or does anyone else think that it is one thing to have all these warranties and payments of compensation printed on the box --- and quite another to make a claim, especially a substantial claim, on one and actually get a payout?
That's what I suspect.getting the payment must be a pain in the neck in terms of proving you deserve the payment
Actually Thad, at least in the case of Belkin, it does work. They offer a substantial amount as compensation and I have heard of a few cases where they have paid.
That means, even Belkin protectors fail after all.
There can't be absolutes....
True. Just wanted to highlight the failure part to show that there is nothing special about Belkin to make it fail-proof.

I do understand that. Actually, my post must be read in conjunction with the one below (especially that I've highlighted) and that of Venkat's and just to imply that Belkin may not be any better than those listed below.A well constructed strip will have better material, tighter contacts, better cables, fuses and other material that can tolerate fluctuations in voltage. But if you pass 2000 volts through a system that can take 440 volts, all materials do have a tolerance limit.

Brilliant idea (as usual) I think Venkat has already posted what to do.hyeah:I was just thinking- is there a way to make my belkin fail so I can claim a fat belkin cheque - so that I can upgrade?
There are some good reasons why insurance companies do not pay out without good evidence
