→Questions on AFCI behaviour under non-ideal power source conditions: 0.1 to 2.0 MHz characteristic |
|||
Line 72:
Not knowing exactly how they work (since that information is lacking), I'd like to know how AFCI's would behave if I switched power over from city main to generator power after a power outage (and also back). Or when there is a thunderstorm in the area. Is "spectral purity" from a generator (or city power) required for proper AFCI operation? I'd hate to fire up my generator only to find all my household AFCI breakers keep false-tripping on it. If this cannot be answered, then I would question whether AFCI technology is sufficiently reliable/mature for mainstream use.--[[Special:Contributions/71.10.145.225|71.10.145.225]] ([[User talk:71.10.145.225|talk]]) 23:36, 19 November 2014 (UTC)
:I researched it a year ago or more but have not gotten around to adding it to the article. I found that arcs have a repeating pulse pattern in the 100 kHz to 2 MHz range and this is the key characteristic that most—if not all—AFCIs are triggering upon. Generators and thunderstorms do not have those characteristics, so an AFCI would be safe with any combination of common power sources, even when struck by lightning. —[[user:EncMstr|EncMstr]] ([[user talk:EncMstr|talk]]) 05:54, 20 November 2014 (UTC)
