I have 6 DC power supplies 0-100A, 0-40v, that use saturable
reactors/magnetic amplifiers to achieve regulated voltage output.
Except that you don't deliberately want a line
reactor to saturate and it's not a magnetic amplifier.
There are a couple of things it might be used for.
One is between a VFD and a load. A VFD output
is a series of steps and since the reactor limits
instantaneous current, the steps get smoothed out.
Likewise, since the reactor limits instantaneous
current, they are used to keep short-circuit
fault current down to a reasonable level until
a fuse can blow or a breaker can open.

So I've got this box that's been sitting around in the yard for about a year
now. Says Trans Tec line reactor. Three phase, gives PN, current rating
etc.
When I open it up, it just looks like a transformer except that it has three
coils around three metal cores.
This works as some sort of filter by using the three phases against
each other? But I don't quite see the point.
Can anyone illuminate?
