I have a converted VAX 6320 in the basement...
My company is currently in the process of decommissioning a
20KW 480/277V generator. If I can rewire that to 208/120V it might
just end up comming home with me to live.
What we did when we had VAXen in an industrial park in North Columbus
that only provided a 480V feed to tenants, was to go with a 2-drawer-
file-cabinet-sized transformer. Obviously, you'd have some loss
through another level of conversion, but it might be easier than
rewiring a generator.
Occasionally they are tapped for either. I haven't seen it yet, but I have
my fingers crossed.
That and a small UPS will make me totally
independant of the power
grid!
But at what cost per kWH? Rates around here are well under $0.10/kWH.
Might even be as low as $0.07/kWH, off-peak (not summertime ;-) What
fuel source does that generator take?
Natural gas. It'd be just for backup, not to replace the grid. After
watching a few automatic transfer systems in operation, I just can't hardly
resist. What would go better with a large, unnecessary computer than a
large, unnecessary backup system? :)
