ZeroSurge 2R15W Surge Protector Review

[fpitas]

Nothing surprising here. I have used these devices (also similar to Brickwall) and never have I seen any assertion that it will improve 'quality'. That is not its purpose. It is a surge suppressor and it works great. I have never had a surge hurt equipment protected by these while I have other electronics in the same house damaged from the surge that did not have these. I have 1 that is 15+ years old and still works great which makes its yearly cost low. They are not a one time use.

I think some of the confusion comes from the Zero Surge ad copy:

Non-sacrificial filter technology repeatedly suppresses worst case surges and removes EMI/RFI noise disturbances from the power line without wear or degradation to the components

Neil Muncy provides a primer on how surge suppression works, how MOV's work, and the advantages of series mode surge suppression in audio systems.

I don't believe that EMI/RFI filtering is directly part of series mode surge suppression.

Thanks for pointing that out. My reading of Amir's test was he was taking the raw power out of the rack. While not pristine, there were no 'disturbances' in this signal, just the typical, all day long, noise. These surge suppressors are not cleaners. I think Amir would need to inject a large high frequency noise component (disturbance) to test the Zero Surge suppression capabilities. Amir uses the word filter but I may not use that word as I read the ad copy is suppressing a surge (disturbance), even in the EMI or RFI range. I consider filtering or power cleaners to be different than dealing with disturbances. I do agree that he term conditioner in the ad copy is not the best word, but I interpreted that word based on what follows. I think Amir's graphs do show some reduction in the high frequency range - perhaps this noise could couple into and interfere with operation of routers, modems, and the like - not sure.

It's open to interpretation just what they were trying to say. In any event, it doesn't do much, if any filtering, in the sense an EMI/RFI engineer would recognize.

Just an FYI as I haven't read the whole thread. The original owner and patent holder, Rudy, told me back in '96 or so that almost all surge-based disruptions to devices in the home are not protected from whole house surge protection because the majority of damage is caused by other devices in the home. We spoke at great length, and he made his bucks consulting to utility companies. not selling his surge protectors. I own many of their devices and the oldest one is from '97 or so, still kicking. They even asked me to send it in so they could test it after 10 years (all on their dime) -- checked out fine. Give Zero Surge's Donna a call (pretty sure she's been the longest term employee and has pretty good tech chops).
