To obtain reliable operating of HTS cable system, temperature and pressure are commonly used as condition monitoring parameters. However, the sensors for the parameters are attached only at the terminals or joints of the HTS cable; therefore, the conventional parameters are not suitable to detect the inward change of the HTS cable. In this paper, tangent distance-based template matching (TDTM) coefficient is proposed to monitor the condition of the HTS cable. TDTM technique is applied to time-frequency domain reflectometry (TFDR) which is an advanced fault localization technique, and the TDTM coefficient is calculated during the template matching. A single phase HTS cable is utilized to verify the performance of the TDTM coefficient, and baseline results are measured at 300 K and 77 K in the test bed. It is expected that the proposed TDTM coefficient can be used for stable operation and monitoring of the HTS cable system.
