Three-phase belted High Temperature Superconductor (HTS) cables have compact dimensions and small inter-phase magnetic interference, and have been applied in the Demonstration Project of Domestic km-Level HTS Cable System of State Grid Corporation of China. The three cores of three-phasebelted HTS cablesare bundled together in the same low-temperature bellows, so a single-phase fault may cause the quench of other two phases, and even lead to an overall failure of the three-phase belted cable. Based on the cable body characteristics, cable termination characteristics and cooling system characteristics of the three-phase belted HTS cables, the related online monitoring parameters and monitoring methods are proposed. The design of an online monitoring system for the three-phase belted HTS cables is introduced.
