Re: Controling a Pole Pig

Without knowing all the exact data for the exact model number of the
transformer you have, I would suggest using an external non-saturable core
inductor for power limiting.  Even if you could contact the manufacturer
they would probably be reluctant to provide the information fearing you
might be a competitor.  A resistance of 0.5 Ohm, 10 kw, resistor in series
with a suitable inductor will provide very smooth operational control
without problems.
