Abstract

This study discusses the application of Partial Electrical Connector (PEC) in various patterns on high-temperature superconducting (HTS) coils. The PEC is a technology that partially attaches metal foil to the coil surface to form a direct current path between the turns, primarily aimed at protecting against sudden discharge accidents in no-insulation (NI) coils. A small sample of NI coil was fabricated with 60 turns, and a 10

$\mu $

m thick PEC was installed to connect the turns. The PEC was applied to areas that covered 1/8, 1/4, and 1/2 of the coil surface to conduct charge tests and sudden discharge experiments. The experimental results confirmed the possibility of controlling the contact resistance by adjusting the amount of PEC. This research aims to optimize the protective performance of the developed contact resistance control technology according to magnet specifications, making it a useful technique for the protection of large magnet systems in the future.
