Control of Shunt Capacitors and Shunt Reactors Energization Transients

Transients produced upon the energization of capacitor banks and shunt reactors may be harmful for the capacitor or reactor itself, for the switching device and for the adjacent system components. One of the most modern countermeasures for the reduction of these transients is controlled switching. In the present study, an overview of the restrictions concerning the application of this technique for the safe switching of capacitor banks and shunt reactors is presented and the benefits of its use taking into account these restrictions are investigated.
