Assesment of over-current protection for superconducting cables [PDF]
IET Conference Proceedings, 2022 The objectives of the studies presented in this paper aim to assess the sensitivity and the stability margins of conventional overcurrent protection schemes for the protection of Superconducting Cables with High Temperature Superconducting tapes. The ultimate goal is to identify the limitations and particularities of the conventional over-current ...
