Résumé

The application of high temperature superconductors (HTS) in power engineering requires both efficient and reliable cooling. Several superconducting cables and fault-current limiters have been designed and installed by Nexans and were already thoroughly field tested. Dependent on the cooling power, temperature and pressure conditions, various solutions were realised and have resulted in different experiences during the field tests. Each system shows specific advantages and drawbacks, and in some cases improvements had been established even after commissioning or during the test period. The operating behaviour was not satisfying in all cases since high effort would be needed to ensure continuous operation and higher efficiency. A main reason is seen in the fact that the typical cooling demand is in a range of a few kW, a domain where large-series coolers are not available to date.
