Abstract
An electric transformer comprising a primary coil and a secondary coil each constituted by at least a first coil formed by winding one or more metal-matrix superconductive conductors. The first coil of the primary coil or of the secondary coil is connected in series with at least one second coil formed by a solid superconductive tube machined to form a solenoid, the second coil being disposed coaxially with the first coil. This design contributes to protecting the transformer by means of its current-limiting effect.
