An engineering formula to describe the AC loss of BSCCO/Ag tape

An engineering function to describe the AC loss of BSCCO/Ag tape conductors is developed. For a wide range of transport currents and magnetic fields ( with different orientation) the loss is described with an uncertainty of 10 %. The equation is based on the analytical expressions available, BSCCO/Ag tapes used in power applications at liquid nitrogen temperature are fed wit h an AC transport current and exposed to an AC magnetic field. The magnetic field in a device has different orientations with respect to the position of the conductor in the de,ice, In this contribution AC loss measurements f or simultaneously: applied magnetic field (with different orientation) and transport current are presented for a high quality tape conductor that is u sed in a transformer coil, The results are separated into a magnetic and a transport current loss component.
