The questions left to be answered for Vocus is why did it take 12 hours
to restore one rail. Where was the static bypass and failing that where
was the maintenance bypass. Im guessing that's what it's on maintenance
bypass now and the slow action may have something to do with the public
holiday in Vic..
I shouldn't speculate. But it is fun.
Something seriously let go in that UPS. If i had to put my electrical
engineers hat on I would say their load capacitor maintenance was not
done and let go. Or someone was working upstream and broke the
natural/earth bond. But there's a lot of parts in a system like that ,
most modern DC UPS setups are fairly robust. I once had 3 strings of
batteries catch fire and melt down and the UPS didn't miss a beat other
then spewing a lot of alarms. We moved strings around on the fly and
nobody even noticed.
The other things that seems odd is why did an A failure trip B. Sounds
like a single supply is at surge/break capacity. Also a worry.
But in the end we all have redundancy around 530 Collins right ? Right ?
