Abstract
An electrical fault mitigation system includes a mitigation device including a containment chamber defining a cavity, a first electrode positioned within the cavity and coupled to a first conductor, and a second electrode positioned within the cavity and coupled to a second conductor. The mitigation device also includes a first voltage source, and a plasma gun positioned within the cavity and configured to emit ablative plasma using the first voltage source to discharge energy from an electrical fault. The system also includes a first voltage limiter device configured to limit a voltage of the first conductor from increasing above a predetermined threshold to prevent a second voltage source from generating a second electrical arc between the first electrode and the second electrode when the second voltage source applies a voltage across the first electrode and the second electrode.
