AC traction feeder transformers

AC traction feeder transformers are used between normal three-phase AC networks and single-phase catenary systems. They are often equipped with an on-load tap-changer (OLTC). Their strong structure is specially designed to resist repeated short circuits during the operation, which are common in electric railways.
