Abstract

A novel method for AC loss measurement of a long length high Tc superconducting (HTSC) wire has been investigated. An 8 m long (Bi,Pb)2Sr2Ca2Cu3O10+x Ag clad multifilament wire was selected to prepare a special sample in which the inductive voltage induced by AC transport currents can be cancelled. Consequently the resistive voltage of the HTSC long wire can be measured. The HTSC sample has been tested at 77 K with AC transport currents up to 3Ic and at various frequencies from 10 Hz to 1 kHz. The loss of the (Bi,Pb)2Sr2Ca2Cu3O10+x Ag clad wire related to its zero field AC transport current characteristics has been obtained experimentally, and results also prove that this method is effective and useful for AC loss measurement of a long length HTSC wire.
