Re[2]: Ballasting a Pole Pig

Hello Interesting,

I never thought of putting them in parallel.  If there is a 100V 
difference in the output voltage of each transformer, for example 1 
NST is 15.1KV while a second might be 14.9KV would they get stressed 
that way if placed in parallel? Or does a 100 volt not much to an NST?
