A new kind of superconducting current limiter

Abstract

This paper deals with a new kind of superconducting limiter. Usually, superconducting current limiters are based on the transition from superconducting state to the normal state by overtaking the critical current. This new superconducting current limiter has no current transport in the superconductor. Indeed, in our structure, the limitation is based on the saturation of a high temperature bulk superconductor by the magnetic flux. We show that our structure enables one to limit the current.

The design of an original structure of current limiter

“…In a previous paper [1], we studied a new kind of superconducting fault current limiter. It is based on a screening effect of a superconducting plate inserted between three copper coils.…”
