     On the ballasting transformer, the 11 kV winding will not be connected to
anything, so since no current can flow, it might as well not exist. This
should
just leave the primary magnetizing reactance. This should present itself as an
inductance which I can vary by altering the gap in the core. This is the
inductance I want to use as a current limiter. ( That's my theory anyway)
