We present research work collaboration between the University of Texas at El Paso and The National High Magnetic Field Laboratory. This work presents a series of measurements of AC losses in multi-filamentary Bi-2223/Ag tapes using a calorimetric method as described by Ashworth and Suenaga. The AC losses were investigated at liquid nitrogen temperatures (77 K) for different AC currents and in frequency range form 50 Hz to 500 Hz. The results are compared with the Norris ellipse model for calculating self-field loss in high temperature superconducting tape.
