Abstract

The relationship between the critical current density and flux flow resistivity in a Bi2223 bulk for fault current limiter application was experimentally investigated. The distributions of J_c and voltage along the longitudinal direction were measured as well as the transport current. As a result, it was found that the flux flow resistivity is higher at positions of lower critical current. Measured results were numerically analyzed to obtain an empirical expression for the flux flow resistivity as a function of the critical current density, accumulated Joule heat and transport current.
