A valuable solution to the voltage rating limitation of gaseous helium (GHe) cooled HTS power devices is demonstrated through the use of cryogenic gaseous mixtures of small mol% of gaseous hydrogen (H 2 ) balanced with GHe. An 80% enhancement of the

This paper presents new approach to using Partial Discharge (PD) data for the prediction of the Remaining Useful Life (RUL) of dielectric materials undergoing breakdown. The method presented uses a thermodynamic macro-model in conjunction with an art

Gaseous helium at high pressure is regarded as a potential coolant for superconducting cables. The dielectric aspects of cryogenic helium gas are both complex and demanding. In this experimental study, we looked at the interface between a smooth epox

The high voltage bushing forms a critical part of any termination on cables, transformers and other power system devices. Cryogenic entities such as superconducting cables or fault current limiters add more complexity to the design of the bushing. Ev

High-temperature superconductors (HTS) allow power cables of substantially higher current density than conventional copper or aluminum cables. This is important for applications where a low mass and a low volume are critical such as naval, aeronautic

The novel type of cable under consideration is cooled by gaseous Helium at elevated pressure. Helium is known for having poor electric breakdown strength; therefore the dielectric capabilities of this type of cable must be tested under conditions sim

The results of experimental determination of surface flashover breakdown voltage under high voltage ac and dc for cylindrical G10 are presented. The results are analysed using Weibull statistics and are compared with theoretical field calculations ob

Successful validation of the dielectric design of high temperature superconducting DC cables cooled with pressurized helium gas circulation is reported. The dielectric design features were developed based on the tests of several short sample cables.
