| Abstract |
A hybrid medium voltage breaker consisting of a power electronic switch (PE) by-passed by a parallel mechanical switch is presented in the paper. The main operation modes and the performances of a 12 kV apparatus with 25 kA short-circuit current capability are introduced. The results of the experimental tests confirm the electrical behaviors foreseen by the simulations during the design phase. The uses of the apparatus in MV applications as AC fault current limiter (FCL) and DC circuit breaker are presented and discussed. |
