Abstract
We have developed a calorimeter with a sensitivity of better than 1 mW/m fo r measuring AC losses in HTS multi-strand conductors for superconducting po wer transmission lines over a temperature range of 64 K to 80 K. By choosin g a temperature difference technique we eliminate the need for corrections due to heating at the cable end connections. Use of a three-phase configura tion allows measurement of single-phase, three-phase, and coupling losses. The 60 Hz calorimeter power supply has a capacity of 2500 A rms.
