The authors have tested the response of Bi-2223 tapes in over-critical current conditions with a view to exploring this material's prospects for fault current limiter applications. Silver and silver-alloy clad multifilamentary tapes have been put in series with a transformer and a resistor. Currents exceeding I/sub c/ were allowed to flow through the(More)
The mechanism limiting the transport critical currents of long-length (Bi,Pb)/sub 2/Sr/sub 2/Ca/sub 2/Cu/sub 3/O/sub x/ tapes is still debatable. Such knowledge is important for improving the current performance of tapes for their use in superconducting applications. Transport and magnetic measurements have been used to study the current connectivity in(More)
