Just curious:
What is your maximum load in kVA when system(s) are running?
What is that in $$/hr?

So, who has run 3-phase to power their MG set and
HVAC for their mainframe?
Extra points for chilled water and even more for a cooling tower for said
water.
I have 600 Amps of three phase service.
I also have motor generator and solid state converters to make about
135 kVA of 400 Hz power, providing everything gets fixed.
Oh, and (I think about) a 25 kVA 100/200 Volt transformer, in case of
Japanese machines.
So there.

I haven't rewired for computer stuff yet, but I ran a conduit to my radio room and
brought in a 20A 240V circuit, a 30A 120V circuit, and two 20A 120V circuits. I don't
know yet how I'll deal with my new computer collection in the next room.
It looks like I'll be picking up a 400 Hz motor-generator set which will live out in
the workshop. I don't know what I'll power with it, but I have a chance to grab it
for free before it goes to the trash man. I'd also be interested in an 800 Hz set if
another one shows up, since I have some WW2 Navy gear that uses 800 Hz power. I plan to
convert a solid-state inverter to provide 800 Hz for it, but it would be neat to also have
a working example of "Here's how not to do it if you have a better option".
