Abstract	We developed an electric method to measure AC transport current losses in HTS tapes placed parallel on a flat plane to study on influence of magnetic field produced by the neighboring tapes on AC loss characteristics of a tape in an assembled conductor. To measure the AC losses in a tape in such arrangement electrically, proper cares for potential leads arrangements are necessary to avoid spurious loss components mixed in the measured data. In our method a combination of spiral and rectangular loops was used. Configuration of the loop arrangements was determined by a study of energy flows among the tapes. The validity of the method was verified by a calorimetric measurement conducted with the same arrangement of the tapes. The experimental data showed that the AC losses in the tape were significantly affected by the magnetic fields produced by the neighboring tapes.
