Tried building a giant jacob's ladder with 50 kva worth  of pigs (25 kva on
each electrode, 34.5 kv each antiphase to each other (in essence 69kv))
without hardly any limiting (except the tiny leakage inductance) and with
the tops removed to keep them from exploding. Don't know what the actual
power draw was, but it was popping 800A worth of breakers in 5 seconds or so
(made the drop wire from the pole quite warm in the process). The arc spread
over 17 feet before the breakers popped (which was over 4" thick and bright
as a welder, which made it hard to look at directly without looking at it
through dark glasses or a trash bag "lens"). The local utility of the town
of 1300 at the time (Stanberry, MO) actually went and asked all the major
machine shops/welders/factories what they were running. They were not
particularly amused when the eventually found out that the brownouts were
coming from my backyard, not to mention the local population being annoyed
that they're electronics were shutting drown from too much voltage drop.
Didn't think that utilities were that sensitive considering thinks like
partical accelerators and fusion reactors pull 50MW for minutes at a time at
the flip of a switch. I certainly hope that I'm not the one responsible for
the blackout back in August....
