5/20: Epic Conclusions, part 1 TCC Orchestra, John Falskow conductor 7:30 PM - FREE TCC Building 2 FB Event: https://www.facebook.com/events/569213183250060/ We’re playing Wagner’s Overture to Die Meistersinger von Nürnberg, and Mahler’s Symphony No.1 - the Titan. These works were composed for large orchestra. What a sound!

Thats a gliding scale... if system A breaks at DUT1 of 1.0seconds B & C might die at 5 and 10 seconds, giving plenty of time to patch the systems. System A does seem to live on the edge already, maybe a good candidate to patch earlier...

Another approach is to ignore the problem and just replace the units if/when they die. That could be a disaster for long term customer relations, but might be appropriate for a home lab setup. -- These are my opinions, not necessarily my employer's. I hate spam.

The alternate (AC) path down through the middle of California is a apparently a bear to keep stable, and transients can take tens of hours to die out. After all, that transmission line is starting to be a significant fraction of a wavelength at 60 Hz. (lambda in free space is 5000km.. prop velocity on a power line is quite a bit slower)

I remember a couple years ago we had a transformer die (thankfully it was a passive failure and not a massive fireball on the pole). People were wondering why their machines weren't working (but the lights were on)... Sure enough hooking up a meter and the high leg was dead... I did read somewhere that this change might have an effect on demand meters?

Things that tend to die are FETs that are switching power.. they don't have much voltage margin on the gates and dumping a bunch of charge from a single event might push it over the threshold and you get a gate rupture (SEGR). SEU and related SEFI are probably pretty unlikely.
