Current Distribution Analysis of Conducting and Shield Layers of HTS Power Cable Under Utility Fault Condition

One of the most important issues in the design of a HTS power cable is the induced current between conducting and shield layers under fault condition. The current distribution of conducting and shield layers is changed due to the fault current. Conducting and shield layers are coupled magnetically. The analysis of current distribution in HTS power cable requires understanding of the magnetic coupling between the conducting and shield layers. In order to study the phenomenon mentioned above, a solenoid type of HTS power cable model which includes both conducting and shield layer is actually manufactured in this paper. The current distribution of conducting and shield layers is evaluated by real manufactured solenoid type of HTS power cable model. The results obtained through the experiment and analysis would provide important data for the design of HTS power cables and valid information for their installation in power system.
