That's a very good news.

Many configurations are possible.

Ha,I suppose you followed recent maggy threads very
closely,didn't ya.

Let's hear from others.Nice to see you got interested
in 3-coil OLTC system personal project.
You could first crank out your 2-coil system  to the
maximum power imput at various BPS ,record arc
lenghts,and then convert the system in 3-coil one.
Performance comparations should come as the last step
.
cheers,
Boris
