M. Marc Lacroix and Pierre Taillefer from VIZIMAX and M. André Mercier from IREQ (Hydro-Québec) teamed up to present the CIRED Papers on the 23rd International Conference on Electricity Distribution.
”This paper describes the benefits of using controlled switching technology on medium voltage circuit breakers. The availability of affordable control switching devices (CSD) has allowed this technology to be deployed in medium voltage applications (MV). Technical and economic benefits can be expected, similar to those experienced by transmission or generation utilities....
With the increasing worldwide demand for energy, most power systems, including distribution systems, must be operated close to their maximum rating. Since security margins are reduced, transients resulting from voluntary CB switching operations can cause unwanted protection trips of the entire system. Controlled switching of circuit breakers is an approach used by several utilities to mitigate voltage and current transients"
