Both AC transport current and magnetic field which are generated by the AC transport current lead to energy loss so called transport AC loss in power equipments using superconducting tapes. The transport AC loss is closely related to stability and efficiency of superconducting power equipments. Therefore, we need to deal with the transport AC loss characteristics of the superconducting tapes under various conditions. In this paper, we investigated temperature dependence of the transport ac loss with respect to the superconducting tape array geometry. The transport AC loss was measured by an electrical method. The experiments were carried out at temperature from 63 K to 77 K. We proved validity of the measurements by a finite element method. Measured data showed that the transport AC loss was influenced by not only superconducting tapes array geometry but the operating temperature. Proposed results in this paper would be utilized to design superconducting power equipments.
