✦ Synopsis

The high temperature superconducting magnetic energy storage (HTS SMES) stores electric power in the form of magnetic energy, and then converts it to electric energy. For the operation, the HTS SMES must have a cryogenic temperature.

The cooling methods for a cryogenic temperature are divided into an immersed method and a conduction cooled method. The immersed method is a direct cooling method that immerses the superconducting magnet into a cryogen. On the other hand, the conduction cooled method is an indirect cooling method that cools a superconductor through thermal conduction with a cryocooler.

This paper classified the structures of insulation according to cooling methods, and studied the insulation characteristics of each insulation factor.
