A novel energy efficient SFCL with a silver-free contact switchgear for application in electricity and transportation.

A novel energy efficient SFCL with a silver-free contact switchgear for application in electricity and transportation.

A novel concept of a switchgear based on the combination of an AC superconducting fault current limiter (SFCL) and silver-free electrical contacts is proposed. In the combined system SFCL+switchgear, it is possible to employ cheaper materials for electrical contacts. The SFCL device includes inducti...
