Re: 3-phase reactor

Original poster: "Sean Taylor" <sstaylor@xxxxxxxxx>

Just  realized that I messed up on the math a little - I was thinking
15 mH, not 0.15 mH.  Anyway, as Terry said, a test with a know AC
voltage/frequency and an ammeter will give you a good idea of the
actual inductance.

It is entirely possible that the inductor you have is just for a line
reactor, not a substantial current limiter.  And, sorry Matt, but I
missed your original post where you said " three separate coils wound
on the same core".  I would just use it for a core, take it apart if
possible to add an air gap, and adjust the current limit by varying
the gap.

These kinds of three-phase reactors go by on eBay all
the time.  They don't seem too useful (in the TC
world).  Even at 1.5mH, you're only talking about half
an ohm at 60hz.  It'll pass hundreds of amps before
you even get to 120V, yet it's only rated for 24A.
I'm having visions of smoke :-)
