“…Additionally, selecting the dielectric insulation system, where the decision between solely gas insulation or composite insulation of solid and gas systems, significantly impacts performance. The performance parameters include partial discharge inception voltage, cryogenic heat transfer and thermal management efficiency, the operating voltage, operating current, and the system's ability to withstand faults without catastrophic damage [6].…”

“…Electric power systems of large ships and aircraft are expected to be at 100 MW and 40 MW, respectively [1]- [5]. For the specific power demands of both electric transport platforms, it is necessary to employ medium voltage levels [6], [7]. As a transformative technology for power distribution in electric transport platforms, high-temperature superconducting (HTS) power cables are attractive due to their exceptional current-carrying capability.…”

The need for protecting the cryogenic infrastructure during a fault in high-temperature superconducting (HTS) power distribution systems of electric transport platforms is highlighted. A dual grounding scheme with an isolator between the electrical and cryogen flow paths of HTS power cables is needed. Finite element analysis of the electric field distribution of the vacuum jacketed isolator showed electric field intensity at the triple points. The electric field intensity at the triple points is reasonable if high vacuum quality is maintained. There is a need for further investigations for design validation with experimentation of practical designs for effective isolation and protection of cryogenic infrastructure from damage during an electrical fault in a section of the power distribution network of electrical transport platforms, such as an electric aircraft or ship.
