Maintien de la fourniture pendant un défaut monophasé moyenne tension : l'expérience acquise au poste de Guebwiller : Transport et distribution de l'électricité : le régime du neutre en moyenne tension

The french national electric utility has conducted technical feasibility and economic viability tests on an original solution capable of maintainting uninterrupted supply during long outages without altering the electrical characteristics of the medium voltage power network. This solution features a shunt-impedance circuit breaker for bypassing the fault at the substation where it originates, a test system for detecting dielectric weak spots throughout the network and special protection systems
