Re: [TCML] Can i use an NST as ballast ?

["McCauley, Daniel H" <daniel.h.mccauley@xxxxxxxx>]

If you are looking for an easy solution to ballast one of the common 14.4kV GE potential transformers, look below.

Terry Blake came up with the great idea of using a 500ft spool of 12AWG stranded wire from Home Depot as the ballast.  When wired in series with the 115VAC input to the potential transformer, it limited current to about 240mA output at 14.4kV.  What a great solution!

You could probably also scale this for use with other transformers accordingly.

Of course, for a pole transformer, the best ballasting solution is a Lincoln Arc-Welder which can be had for very inexpensively on craigs list.

Ok, the power output from my potential transformer will never be more than 
the ballasting NST. So if my NST is rated 500VA i will get 500VA or less 
from my potential transformer. But if i add two 500VA NST:s in parallel i 
get 1000VA or less.

Guess its time to find some MOT:s.

Thansk for the help guys.
