Abstract

Superconducting fault current limiters are devices capable of solving the problem of extremely high fault currents in power networks, while simultaneously providing very low insertion impedance under normal operating conditions of the network. This chapter discusses the general requirements of the current limiters and reviews various types of superconducting limiters. The main attention is given to their designs and operation principles, and a comparison of the different designs is presented. Possible applications of the limiters in power systems are discussed. ...
