A Device of Current Lead for Fault Current Limiter of YBCO Film

In this paper, we propose non-soldered current lead was introduced which has low contact resistivity for fault current limiters of YBCO film. Carbon/Cu has good thermal conductivity, electrical conductivity and chemically stable, and so forth. Therefore it seems to be suitable material of current lead for current limiters of YBCO film. We have investigated electric field-current in field of 0-130 mT and quench characteristics of a YBCO film. Experimental results show that characteristics of transport is all right using Carbon/Cu-current lead.
