摘要：
We report a simple technique for the measurement of energy losses in HTS tape carrying ac currents in ac magnetic fields at liquid nitrogen temperatures. This method is based on measuring the temperature rise of a thermally insulated tape and in the present form is able to measure losses down to 0.01 W m(-1). We present data obtained by this method confirming previously published results for the losses at 100 Hz due to in phase ac currents and magnetic fields as measured electrically. Using this calorimetric method we are able to measure the effect of phase differences between current and field. (C) 1999 Published by Elsevier Science B.V. All rights reserved.
