Representative work: The dc circuit breaker is an indispensable building block for dc network systems. Hybrid circuit breakers that combine mechanical and solid-state switches have more potential to be utilized in dc distribution networks because of their lower conduction losses and fast interrupt speed. The efficient energy dc interrupter with surge protection (EDISON) removes any solid-state circuit in the main current path, thereby substantially reducing the conduction losses during normal operations. However, it requires a dedicated control with fast dynamics because any false triggering of the mechanical switch or solid-state switches of the breaker would lead to a commutation failure and a potential unquen Abstract High-temperature superconducting (HTS) direct current (dc) power cables allow high levels of power transmission and distribution at low loss and can be tailored to effectively limit fault currents. HTS Conductor on Round Core (CORC ® ) power transmission cables offer additional benefits over other HTS cable designs, including a much higher current density and a higher degree of flexibility. These benefits make CORC ® cables most suitable for applications in confined spaces where tight bends are required, such as onboard naval ships and in data centers. The development of CORC ® power transmission cables for operation in pressurized helium gas is desc
