Re: capacitive or sat.reactor ballast?
Hi Tristan,
Reactive current limiting is used by Maxwell on their 100 kW 100 kV
power supply. It works great. Be cautious of one thing though. If the
system resonates near 60 Hz the pig will fry. A little resistance could
help prevent this by dampening the circuit. Capacitors are a lot lighter
than arc welders. A lot cheaper too. You could use a bank of heavy duty
switches to choose the capacitors. This would give you adjustable current
limiting. Also, put a heavy duty fuse in the primary line. If a capacitor
shorts out the fuse will save the pig.

Greetings to all,
I have been browsing around the ballast posts and since I have just
got my first pig (wich will be another post) I need to start thinking
about ballasting.
I non-coiler suggested that I use capacative ballast, and since I
havent heard of this being done on the list I assume there is something
bad about it...please fill me in. He says that a 60uF cap will pass
about 5A and I could make a parallel bank of them and put em in series
with the pig. I actually just got a 3phase power monitor(as big as two
washmachines+ACE-) and it had a bunch of 60uF 330V caps. I assume 330VAC is
sufficient for 240V pig?
Also, someone else suggested I make a saturable core reactor using the
core of my burnt out 50A variac. Any suggestions?
I always appreciate constructive criticism,
