Aspects regarding the controlled switching of the shunt reactors

The paper focuses on controlled switching for the circuit breaker of a shunt reactor. Controlled switching is a modern technique used for the adjustments of the transient stress witch appear at the switching process. This paper presents the controlled switching and perspectives according to recent theoretical and technological aspects. Also, it is presented the contributions of controlled switching regarding the energizing/ de-energizing of shunt reactors. The analysis of the optimum moment for the controlled opening and closing is determinate as a result of simulation. The transients caused by switching of shunt reactor are modeled and simulated in ElectroMagnetic Transients Program (EMTP) software.
