AC transport losses in a single superconducting tape, double- and triple-stacked Bi-2223/Ag superconducting tapes were measured by use of electrical method. The measurements were carried out at 77K with the frequency of AC transport currents ranging from 50 to 1000Hz. The dependence of AC losses on frequency and the number of tapes in the stack were presented and analysed.
