Greetings folks, We have products that meet all the Surge requirements of NEBS GR-1089, FCC-68 and EMC 4-5. But, the same products are continuously failing in the field due to real-world lightning strikes.
I have spoken to four other manufacturers who make similiar interfaces (DSL) and they all have the same problem : they meet the standards, but fail in the real world. I have two questions for the esteemed people here : 1) Were these standards written based on somebody doing some field evaluations? Has IEEE/Bellcore done any research into what the waveforms really are for actual *real-world* lightning strikes? How do they do that? 2) Is somebody working on re-charaterization of lightning strikes throughout US (eg, the surges seem to be more lethal in TN as opposed to CA)? Would you have the contact details of Working Groups? Thanks [email protected] __________________________________ Do you Yahoo!? Yahoo!
