Michael W. Ryder wrote: I realize this, he has been doing this for many years, but post to educate others who might have been taken in by him. Fine. Just post manufacturer numerical specs that define protection for each type of surge - including the type that typically causes damage. Michael cannot do that because plug-in manufacturers do not even claim such protection. Sales are promoted by undersizing protectors so that smoke promotes more sales. Sales are promoted by installing protection from one type of surge - and leaving the naive to assume that is protection from all types of surges. It would be so easy for Michael W Ryder to dispute what I post. All Michael need do is cite manufacturer numerical specs. No such specs exist because plug-in protectors ... without that all so critical 'less than 10 foot' connection to earth ... cannot provide and do not claim such protection. WHERE did I say that everything you posted was wrong????? As I posted to an earlier post which you seem to have ignored the manufacturers will NOT provide specs to be used by some shyster for a class action lawsuit. My posts were about UPS systems that totally remove the AC circuit from the equation, not about stand-by UPS systems. Whole building grounds will NOT protect equipment from transients without other equipment. Our office installed the above as the first step when encountering power problems. Total effect of zero. Same for an isolation transformer. Only after running the equipment off of batter power did the problems go away. Nothing was ever said about surge protectors as our problems were with transients too small for a surge protector. No earth ground means no effective protection. Protectors from responsible manufacturers have a dedicated earthing wire. Michael will not even provide manufacturer numerical specs because no such protection exists. See above. What do UPSes with effective protection have? Those building wide UPSes also make the short connection to earth using a dedicated connection. Plug-in UPSes have no such earthing connection and therefore provide no numerical specifications. Michael cannot post what does not exist. So he attacks the messenger - and hopes that is technical proof. WHO is attacking who here???? Why don't YOU post some specs showing what your vaunted whole building ground can do??? Because you can't I bet. I post examples of problems I have personally been involved in and the final solution, you post attacks saying I can't provide numbers. Numbers are worthless, results are all that counts. This thread is done for me. |

You have never provided "manufacturer numerical specs that define protection for each type of surge" for any of your favorite manufacturers. Your manufacturers apparently "do not even claim such protection". Any decent plug in suppressor or UPS with surge protection has MOVs from H-G, N-G and H-N as shown in the IEEE guide on surges. They handle common mode and transverse mode surges. You may not be able to figure out how they work, but the IEEE and NIST can. The obvious fix for undersized is not to buy undersized suppressor. No earth ground means no effective protection. Protectors from responsible manufacturers have a dedicated earthing wire. Your religious views on earth ground are not relevant. The IEEE guide clearly describes plug-in suppressors as clamping all wires to a common ground at the suppressor. Earthing is not the primary method of protection. The IEEE and NIST guides say that plug-in suppressors are effective. That also applies to UPSs with built in surge protection.

Bud claims UPSes are effective surge protection and yet does not
provide numerical specifications for each transient type. So many manufacturers to quote from. Bud cannot even find one to quote? Exactly. Bud promotes a myth about protecting from both common mode and transvers mode. Fine. Manufacturer specifications say that? No. Why does Bud claim what even the manufacturers do not publish? Notice the plural - manufacturers. So many manufacturers and yet Bud cannot find even one with those numerical specs? Bud is again posting this myth: The IEEE and NIST guides say that plug-in suppressors are effective. Bud's own citations don't make recommendations. His own citations are technical discussions about what may work and how it may fail. Instead we go to an IEEE *Standard* for recommendations: IEEE Red Book (Standard 141) says: In actual practice, lightning protection is achieve by the process of interception of lightning produced surges, diverting them to ground, and by altering their associated wave shapes. What type of UPS makes that earthing connection? Building wide UPSes have a short and dedicated earthing wire. Plug-in UPSes have no such earthing wire - which explains why those UPS numerical specs don't even claim such protection. Remember those specification numbers that neither Bud nor Michael Ryder provide? IEEE also recommends effective protection in another *standard*: IEEE Green Book (IEEE 142) entitled 'Static and Lightning Protection Grounding' : Lightning cannot be prevented; it can only be intercepted or diverted to a path which will, if well designed and constructed, not result in damage. IEEE Green book also discusses earthing for lightning protection. IEEE says what is required: earth ground. Bud repeatedly denies this. No earth ground means no effective protection. IEEE Standard 141 and IEEE Standard 142 are quite specific on what is required for effective protection: earthing. What does Bud say? Earthing is not the primary method of protection. Bud follows me around everywhere posting some mythical protection without earthing. Some mythical protection that even manufacturers do not claim. IEEE Std 141 and 142 have been quoted to him repeatedly. So why does he even misrepresent IEEE? IEEE is quite blunt about what is necessary AND what has been proven for protection long before WWII. Earthing. Bud will say most anything to deny this 'well grounded' reality. bud-- wrote: w_tom wrote: ... No earth ground means no effective protection.

Again Bud posts accusations and claims - and yet will not even
requote what the IEEE recommends. IEEE Standards 141 and 142 define what effective protection must accomplish. Recommendations in IEEE Red Book and IEEE Green Book are in direct contradiction to what Bud claims and what the plug-in protector manufacturer hopes you will assume. IEEE is quite blunt about what is essential to effective protection - earthing: IEEE Red Book (Std 141): In actual practice, lightning protection is achieve by the process of interception of lightning produced surges, diverting them to ground, and by altering their associated wave shapes. IEEE Green Book (IEEE 142) entitled 'Static and Lightning Protection Grounding' : Lightning cannot be prevented; it can only be intercepted or diverted to a path which will, if well designed and constructed, not result in damage. Bud will recommend plug-in UPS and yet cannot even provide a single manufacturer numerical spec that claims such protection.

Bud says 5 EEs who wrote his citation read the IEEE standards. Yes,
and that is why his citations also define how his protection can be compromised even by a kid with an Xbox. But again return to what IEEE recommends. Not in a technical discussion. IEEE recommendations are in standards that Bud will not even discuss. Why would he discuss a recommendation that demonstrates plug-in protectors as ineffective? Why would he discuss a *standard* that recommends the 'whole house' protector? What Bud hopes you will forget. IEEE Red Book (Std 141): In actual practice, lightning protection is achieve by the process of interception of lightning produced surges, diverting them to ground, and by altering their associated wave shapes. IEEE Green Book (IEEE 142) entitled 'Static and Lightning Protection Grounding': Lightning cannot be prevented; it can only be intercepted or diverted to a path which will, if well designed and constructed, not result in damage. Scary pictures were so common in the 1980s that PC Magazine even had two feature articles on how frequently undersized and mislocated protectors created those scary pictures. Therefore UL has required backup safety devices in all protectors - for decades. Why do recent scary pictures still threaten fire? UL backup system alone is not sufficient. Just another reason why properly sized plug-in protectors are, instead, located in a safer place AND with the 'less than 10 foot' connection to earth. Again, scary pictures because human safety is dependent only on a UL required backup safety device: http://www.hanford.gov/rl/?page=556&parent=554 http://www.westwhitelandfire.com/Art...Protectors.pdf http://www.ddxg.net/old/surge_protectors.htm http://www.zerosurge.com/HTML/movs.html Meanwhile, UL requires certain numbers be lists - numbers for human safety. Manufacturer does not list each type surge and numbers for each surge. Why? It protects only from one type of surge so that you will call it surge protection. UPSes typically contain numbers so small - so few joules - as to be all but no surge protection. Bud hopes you will overlook a pathetically few joules inside a UPS. Too few joules - enough to proclaim protection to the naive. Bud also hopes you forget to ask for protection for each type surge. Why? Where protection does not exist, then numbers do not exist. Those same numbers that Bud forgot to promote in order to promote myths. Those who politicians fear and hate, instead, demand numbers. Protection inside a UPS is typically so grossly undersized as to be ineffective. Bud, who promotes for plug-in protectors manufacturers, fears you might learn why plug-in UPSes and plug-in protectors are so ineffective. He even posts numbers required for UL - human safety - as if that were numbers for transistor safety. Again, he knows he is deceiving you. Bud refuses to acknowledge or admit to what IEEE recommends in Red Book and Green Book ... because plug-in protectors violate that recommendation. bud-- wrote: On Oct 5, 5:25 pm, "w_tom" wrote: ...

UPSes typically contain numbers so small - so few joules - as to be all but no surge protection. Bud hopes you will overlook a pathetically few joules inside a UPS. Not at all. A UPs may not be designed effective for surge protection. One can plug a UPS into a plug-in surge suppressor. . Bud also hopes you forget to ask for protection for each type surge. Why? Where protection does not exist, then numbers do not exist. Those same numbers that Bud forgot to promote in order to promote myths. Never seen - any site from w_ with the stats he requires others to furnish. Another bs argument. Bud, who promotes for plug-in protectors manufacturers, To quote w_: -again- "It is an old political trick. When facts cannot be challenged technically, then attack the messenger.." Bud refuses to acknowledge or admit to what IEEE recommends in Red Book and Green Book ... because plug-in protectors violate that recommendation. Repeat #1. The IEEE published one of the guides. For those who can read and think, IEEE and NIST guides say that plug-in suppressors are effective. Links to sites that say plug-in suppressors are effective: 2 And add the 4 horror picture sites. Your links to sites that say plug-in suppressors are not effective: always 0 And -still- missing - your links to sites that have common and transverse mode ratings for service panel suppressors, ratings which you say are essential - for other people. bud-- |
