Abstract

The Superconducting Fault Current Limiter (SFCL) is one of the most attractive devices for the electrical power network. The inductive SFCL consists of two coaxial windings and an optional magnetic core. The primary winding, connected in series to the circuit, is conventionally made of the copper wire, the secondary is made of a superconductor. The 15 kV class SFCL has been designed. It consists of 7 units. The primary copper winding of units has 27 turns/unit and the operating current is 1 kA. The HTS winding of units is wound with 140 turns of YBCO coated conductor SF12050 tape (SuperPower Inc.). The HTS winding has an internal diameter of 0.455 m. The SFCL is cooled in the liquid nitrogen bath. In this paper, we have described the numerical model and the numerically calculated electric parameters of the 15 kV class inductive type SFCL in the stand-by state and during current limitation.
