Abstract

It is demonstrated that melt cast processed (MCP) BSCCO 2212 bulk material is an excellent candidate for resistive superconducting current limiters. For rod shaped samples it could be shown that a homogeneous voltage of more than 1 V/cm can be established over the whole length of the sample leading to a substantial limiting of short circuit current. The require long lengths of superconducting material can be easily obtained by machining the MCP-tubes into (bifilar) coils. The measured critical current density and its homogeneity over these large lengths were determined and proven to be sufficient for the designated application
