To demonstrate knowledge, define the electrical path that each surge took. If you have damage, then you listed that damage including the incoming and outgoing surge path. Otherwise, you have observations not supported by the underlying science - junk science conclusions. Amazing how many know a surge (high voltage) existed only because a blackout (low voltage) occurred. The word credibility applies.
Have you ever been in a home when it's been struck by lightning?
If you have, then you obviously know what the hell just happened, and not a simply "blackout."
It's a blinding flash of light, followed near instantly by a massive "boom" that will shake the whole house . . . and less than a second after that everything goes off (circuit breakers tripping) . . . and close on the heels of that phenomena, there's a very distinct taste and smell of ozone in the air (or static electricity, if you want to call it that).
Once you've been in a home that's been struck, there's no mistaking it. It's not some simple loss of power. It's a shaking moment that will not just fade from memory.
Routine is for a plug-in protector to earth a surge destructively through any adjacent appliance. A TV’s protector earthed a surge through a portable phone base station in another outlet in the same room. Learned basic circuits to know that portable phone is electrically connected to the same power strip that a TV connected to. Please learn some basic electrical concepts which also explains why that TV’s power strip earthed a surge through a nearby phone base station.
Both paragraphs are facts learned before you can tell us anything about four strikes. Based upon details posted, you have only speculated that strikes existed. And then automatically assumed protectors that do not claim that protection, instead and miraculously provided that protection. How did that protector do what even its manufacturer will not claim? A problem we engineers so often must confront - bluntly. Experts who know without first learning.
So, now you're a full blown expert, eh? An engineer?
Something I've learned from years in the field is that engineers are great with "theory" and design but fail miserably when it comes to actual field experience.
That UPS acts as a filter? Absolute nonsense. You would have known that from facts and numbers already posted. Why did you ignore technology to again post an outright myth? Learn what a UPS does. It connects an appliance directly to AC mains when not in battery backup mode. How does a relay become a filter? Please. Every question in those post not answered only further confirms too much ‘knowledge without first learning’. How does that relay become a fitler?
Relay? Or condenser? There are countless forms of filtering components that are added into circuits - things from simple capacitors that filter small voltage fluctuations, to ground transient filters designed to eliminate noise on the ground channel.
But, obviously, an expert such as yourself knows all about eletrical filters, right?
More questions. Where are numbers that claim any filtering? I install the same filter by purchasing some two cent capacitors at Radio Shack for their inflated 70 cents. What kind of filtering is that? Same filter the your UPS does. But again, you have claimed filtering without also posting the numbers. So again, where is this filter in that UPS? A sales brochure said "Filter" and forgot to include the phrase "Near Zero"? Since it had no numbers, then you “know” that filtering stops spikes and surges?
How does that filter stop what three miles of sky could not? Credibility says you have an answer. Especially when you read those manufacturer spec sheets to know before posting.
Again - I step back to my earlier statements that a UPS is
not, nor should be, the primary form of protection for an appliance.
I'ts filtering is in removing the "dirt" from the input current -
not filtering massive issues. Again, a surge protector is best designed for that . . . I never said it wasn't, and I never said that a UPS is designed to completely replace a surge protector.
You've continued to take my posts far out of context, simply to twist what I'm saying in support of your argument, without offering much in the way of helpful information yourself. All I've seen are some links to pages that equate literally to "scare tactics," with no further linking to other proof to back up
your claims.
Existing filter required in every appliance (including the microwave, TV, etc) by FCC regulations are superior to what that UPS does. Where are you numbers to dispute this? Unfortunately your numbers will only confirm this paragraph. Massive filtering already exists in appliances. But somehow s UPS does filtering? Well, yes. The only filtering is required for its control circuits – while all other appliances are connected directly to AC mains. Another example of 'knowledge without first learning'.
You seem to forget that a UPS is designed for PC systems - not appliances. Although appliances can be plugged into one, there's not much point.
A PSU has little to no filtering of incoming current - it's been a notorious issue amoungst overclockers of small surges in the incoming current being passed along to the hardware . . . it can make a stable rig unstable, and risk unnecessarily damaging components.
But, I guess your knowledge of appliances is just that, and does not apply to PC hardware, correct?
Those internal transients are damaging to appliances? Another myth so insulting because the deception is obvious. AND was exposed in earlier posts - with numbers. Reposting those myths only degrades your credibility. Did you not grasp layman’s reasons why those spikes do not exist?p
Or maybe you just forgot what was posted. If spikes exist, then you are replacing dimmer switches and GFCIs every day. Are you? Please, learn this basic knowledge before posting. Or return to learn from an earlier post. Please stop embarrassing me with those junk science myths. Please learn simple electrical concepts before posting "these small spikes are extremelly damaging to appliances, and even more-so to the PC. " Obviously that is not true – can only exist when someone entertain hype and fear – and does not learn the numbers.
I'm embarassing you? Or are you just being embarassed as the conversation leads further out of your realm?
I'm sorry, but I can't further explain the concept of push/pull over-voltage . . . perhaps you might know the concept as backfeeding.
What are small spikes? Tens of volts. What is the output from a UPS when in battery backup mode? Two 200 volt square waves with a spike of up to 270 volts between those square waves. If appliances are so destructive, then a UPS destroys everything. Please learn reality before posting. How can anyone attribute credibility to your posts after you ignore technical facts; repost "small spikes are extremelly damaging"; promote a virtually zero filter inside a UPS as miraculous.
Did I ever mention anything about a UPS' output when in backup mode? Nope.
Do you keep jumping to this arguement thinking that a UPS is
constantly running in backup? Yerp.
TBH, I don't give a total rat's ass what the output is in backup mode - when that phase has come full round, the rig needs to be properly shut down . . . not weather it out. The use of a UPS
after the use of surge protection devices is to allow for the system to be shut down properly. Instantly cutting power to a rig can be dangerous and damaging to the highly sensitive hardware . . . if
you don't grasp that concept, you might want to quite picking fights and start researching PC components.
So how much does it cost to replace a dimmer switch and bathroom GFCI every hour? Reality - those interior destructive spikes are classic urban myth - never existed - easily promoted so that fear replaces logic.
So, I take it then that you've sat probing a wall outlet all day with a sensitive DVOM?
Or are the thousands of claims from other certified professionals wrong, too?
Please read and comprehend technical facts to protect your credibility. Amazing how those ten volt spikes cause damage when a 270 volt spike from a UPS does not. All appliances - especially computers - already contain protection that make those mythical spikes only further irrelevant.
Well - if you want to keep stouting technical facts, why don't you go ahead and dig them up?
You're whole presence in this thread has been nothing but trolling, IMHO. You continue to overlook what I post, and fail to comprehend what I post . . . then proceede to twist my words around, and argue points that are contradictory to my statements. All the while posting links to scare tactics, then demanding I post up factual numbers, yet you don't want to backup your "technical" information yourself . . . all the while claiming that I don't grasp basic concepts, when it seems that you don't grasp them either.
Good day to you, sir, but I tire of this tepid BS.
