Abstract

This paper presents the design and performance results of a pair of conduction-cooled brass current leads for a resistive superconducting fault current limiter (SFCL) system. The 24 kV class SFCL, which has been recently developed by the KEPRI-LSIS collaboration group in Korea, requires three pairs of conduction-cooled brass current leads operated continuously at 630 A. When the SFCL system is in the fault-mode, the current leads have experienced a 60-Hz fault current of ∼10 kA at 24 kV for 3-5 cycles. In this paper, we present the performance results of the conduction-cooled brass (commercial brass, 10% Zn) leads having a rated current of 667 A operated in a bath of liquid nitrogen.

Bibliographical note

Funding Information:
T HE development of thermally-stable current leads for a su-perconducting fault current limiter (SFCL) having a minimum heat input at the cold-end is very important because SFCL has frequently experienced a fault current, that is 20 times its rated current, when the SFCL system is in the fault-mode. The 24 kV/630 A-SFCL is being developed by collaboration between the Korea Electric Power Research Institute (KEPRI) and LS Industrial Systems (LSIS), which is supported by a grant from the Center for Applied Superconductivity Technology of the 21st Century Frontier R&D Program funded by the Ministry of Science and Technology, Korea. This resistive SFCL system requires three pairs of conduction-cooled current leads.
