Abstract

This work is a contribution to the reliability improvement of the stabilized voltage feeders based on auto-transformer. Into these systems, sometimes, temporary faults could happen during voltage commutations, these can induce short-circuits that can cause several damages to the feeding system. To avoid it, we have designed a new electronic board against the short-circuits, that allows the control of the commutations and allows to stop possible over-currents.
