Re: [TCML] RE: 942C current? Reactor



Hi---

You can use an AC arc welder for a reactor if you wire the 220 V line in series with the 220 into your XFMR and short the welding outputs together. The current is adjusted with the welding current control. You get current of about 24/220 times the set current. A 110V welder would work for small coils. I have used three welders to current limit a 3-phase supply. Welders call this type of unit a spatterbox. They are available at Sears, etc.

yes, I have a datasheet which I will email to you as I can't post on the
List   --- viruses.

You can easily run the 5 kVA unit at 10-12 kVA with no problems.  You will
need a suitable current reactor to control the current.

       Dr. R,
                          Yes, please, more info on the pole pig caps! I
have a nice 5 KVA dual bushing 14.4 KV pig just waiting to be put into T/C
service.

Regards,
Bob

What cost per CD cap are you willing to sell them for?
Also just out of curiosity, how much for the pole transformer capacitors?
Do you have details on that cap anywhere?

Thanks!

We have a large order of MMCs arriving in mid April.

I also have 12 pcs of our .07 uF (70 nF) 80 kV caps for pole transformer
driven coils.

I got a great deal on a used $45,000 foil cap winder, so have been rolling
my own.  We now use them in all of our large coils.

Hi everyone,
I was going to order the 942C series cornell dubilier caps (2kV, 0.15uF
http://www.cde.com/catalogs/942C.pdf ), but am now worried that their
current (amps) ratings are too low for my MOT driven coil. Should I order
the more expensive 941C caps (1.2kV, 0.22uF
http://www.cde.com/catalogs/941C.pdf) although their dV/dT ratings
aren't
as good? Does someone know which are better for the high current output
of
MOTs?
Many thanks,
Etienne
