Abstract
Systems and methods for protecting a series capacitor bank are provided. According to one exemplary embodiment of the invention, there is disclosed a capacitor protection circuit. The capacitor protection circuit may include a capacitor bank, a pilot circuit and a main commutation gap. The pilot circuit and the main commutation gap may be provided in parallel electrical communication with the capacitor bank. Additionally, one or more plasma injectors may be provided in series electrical communication with the pilot circuit. The plasma injectors may be operable to provide partially or completely ionized plasma across the main commutation gap to make conductive the main commutation gap.
