The development of new materials known
collectively as BSCCO (ceramic compounds containing
bismuth, strontium, calcium, copper and oxygen) has
initiated a large number of research programmes around
the world, aimed at creating superconducting devices for
electrical power applications [1]. Research is focused on
a number of applications including transformers,
generators, motors, cables, magnetic energy storage
systems and fault-current limiters. Among these, the
high temperature superconducting fault current limiter
(FCL) is unique in being essentially a new device rather
than an existing application into which high-temperature
superconductors have been incorporated. It is also one of
the applications closest to commercial exploitation.
Given that fault levels exercise a significant influence
over the design of electrical power networks and can
adversely affect system components, the hightemperature
superconducting FCL is likely to be of
major practical importance [2].
