Surge Protectors

this thread is great...i know a lecturer in electrical engineering, he would love this...but i aint gonna do that yet ...as you were :rotfl::rotfl:

ps...i have made a fire and burnt my surge proectors just in case...did i do right?

ps ps..mind you i have fitted the kids with lightning conduits just in case

Sounds like a good plan, kids are like cats they have nine lives.

Adults don't, therefore kids have more chance of surviving a lightning strike

westom you ask us to provide numbers we have offered manfuacturers specs which you have completely ignored like and ignorant preaching preist!

I do not see any numbers. I see "6000 volts 6500 amps" which calculates to 550 joules - near zero protection. I then asked cit_k for the joules number from that UPS. He refuses.

Exactly which number do you refer? Quote it. Don't waste bandwidth with only a URL or “do a google search”. If a manufacturer spec number makes that claim, then post that number. Tell us specifically which number makes that claim. Telling anyone you just know is classic junk science. Where are the spec numbers?

Getting upset also wastes bandwidth. If you have spec numbers, then post each spec number in the very first paragraph. How does that near zero 550 joules absorb surges that are hundreds of thousands of joules?

> I already told you, you can find those numbers very easily with google, ...

... is cit_k again admitting he has no numbers. Subjective claims and no numbers. One sentence could provide the numbers. Instead he posts another long diatribe and will not post any relevant spec numbers. He will not even post the joules for his trivial “6000 volts 6500 amp” UPS. Why? Because that joules number says the UPS is near zero protection. So instead, he posts long winded venom.


That UPS performs one useful function. To provide temporary power during a blackout. To provide opportunity to save unsaved data. So that a rare and destructive surge causes no damage, an informed homeowner earths one ‘whole house’ protector. The effective solution costs about $1 per protected appliance. How much for a UPS? $100 per appliance with near zero protection and no always required short connection to single point earth ground.

Where are those spec numbers? First paragraph - post spec numbers for protection from each type of surge right there. Its not hard - if those numbers existed. Impossible because those protection specs do not exist.

Westom.

You're arguing that surge protectors are a rip-off.

Would it be possible to summarise, in a short paragraph, in simple terms, why surge protectors offer no significant protection?

D.K.

Westom,
I'm trying hard to be sympathetic and understanding. My USP solved my problem OK yes?.
My work is not electronics or computers, it is in mental health.
As far as I am concerned I'll go to bed tonight and I won't dream of surge protectors.... like you might?

It has been summarized in every post. Protection is always about where energy dissipates. A protector is only as effective as its earth ground.

Or again, how do you identify an ineffective protector. 1) It has no dedicated wire for that always required short connection to single point earth ground. 2) Manufacturer avoids all discussion about the item that provides protection - earth ground. And protector that violates either is ineffective. The NIST (US government research agency) is blunter:

Read only one paragraph or pair of paragraphs. That is one reason why some protectors are only profit centers. Provided are tens of reasons why those protectors are not effective.

I do not know how I could have posted this any simpler. Every post ends with the only fact all should know. If only told what to know and do not want to know why, then only read this: Protection is always about where energy dissipates. A protector is only as effective as what provides protection - its earth ground.

I'll take your final summary and work from the ground up.

"A protector is only as effective as what provides protection - its earth ground."

Logically:

We're talking about protecting an appliance beyond the mains point. That effectively means that some part of the circuit has to determine what is more power than the appliance can safely handle, and then dump the excess 'power' into the earth, rather than channeling it through the appliance.

That's what power surge protectors claim to do better than than appliances' own power supplies, and I think specifically they claim to be able to handle power spikes more effectively than appliances' own power supply units (PSU's). i.e., they react faster.

Specifically, what's your evidence against this claim?

Reading your summarised paragraph, I conclude that any surge protector that has a dedicated earth wire and whose manufacturer does not avoid discussion of the role of the earth wire is therefore not proved as as being a unit that, or being the manufacturer of a unit that, provides inadequate protection.

You're obviously a logical sort, so I'm sure you'll see the logical truth of my last paragraph.

Good grief, where did you get that idea from?

OK Weston I'll Join the rest and laugh at your daft logic, if you like, which cannot answer my point.
Happy with your compulsive behaviours, yeah? You're not making any friends. Nobody agrees with you. Is that OK? Do you think therefore it matters to anyone now , are they really concerned what you say or does that not matter to you? Will you now reply "Show me your figures" or can you be less abrasive and politely accept someone else's opinion?
I suspect you will find that difficult and suggest you get some help before you don't have a friend left.
