Understood but I remember seeing scope shots showing it as less dramatic and shrinking with each cycle. Providing I can configure this transformer for an isolating primary, does the restrictive action described above also work on the secondary side? The caps will act like a dead short for an instant but there is a second coil (isolating PT) in the way to dampen this demand. Yes, the first side of the trafo will get the full hit but the isolating part has two offsetting fields, one accepting and the other providing. I know it seems counterintuitive but is it possible for a good inrush limiter on the secondaries, just before the cap bank to sufficiently inhibit the energizing of the primary side?trobbins said:
