Abstract

A small scale inductive fault current limiter has been designed, modelled and tested. The device outlined in this paper utilises a simple ferrite E-core arrangement. Electromagnetic analysis is used to predict its performance and this has been subsequently compared with experimental results. The merits of several different arrangements of the components of the fault current limiter are then outlined. Melt processed thick film YBa/sub 2/Cu/sub 3/O/sub 7-/spl delta// (YBCO) rings have been fabricated. The thick films are in planar form, screen printed and fired on yttria stabilised zirconia (YSZ) substrates. The characteristics of the superconducting rings have been studied and compared in the fault current limiter (FCL).
