AC losses of Ag-(Bi,Pb)SrCaCuO-2223 tapes in combination of transverse external magnetic field and transport current

Abstract

The authors present the results of measurements of the AC transport (self-field) and magnetic losses on silver sheathed (Bi,Pb)SrCaCuO-2223 tapes prepared by the powder in tube method. In the frequency range 30-540 Hz the transport current losses are hysteretic in nature. Losses arising from AC external magnetic field (frequency range 65-207 Hz, amplitude up to 60 mT) are compared with losses generated by AC transport currents. The measured transport loss voltage depends strongly on the position of the potential taps on the surface of the tapes. Losses due to combined AC applied magnetic fields and transport currents are also reported.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
