Ablative plasma gun

An ablative plasma gun comprising:

• a first gun electrode;
• a second gun electrode defining a longitudinal slot;
• at least one dielectric layer having the longitudinal slot between the first and the second gun electrode;
• and
• an opening at distal end of the longitudinal slot to spread a plasma across wide longitudinal distance.

An arc elimination system comprising:

• an arc mitigating device comprising at least two electrodes forming a gap and coupled to a phase or neutral or ground in an electrical power system;
• an ablative plasma gun comprising a first gun electrode and a second gun electrode arranged between a dielectric layer to form a longitudinal slot;
• an opening at a distal end of the longitudinal slot to spread a generated plasma;
• a trigger circuit to generate an electrical pulse for the ablative plasma gun;
• and
• wherein the ablative plasma gun is arranged between the gap;
• and
• wherein the generated plasma lowers an electrical impedance in the gap between said at least two electrodes.

An arc mitigating device comprising:

• at least two main electrodes separated by a gap and coupled to electrically different portions of an electrical power system;
• at least two ablative plasma guns having a longitudinal slot to spread a generated plasma in wide longitudinal distance;
• wherein said ablative plasma guns disposed proximate the gap and main electrodes, the ablative plasma guns configured to bridge the gap between said main electrodes by plasma spread upon receipt of a trigger signal;
• and
• wherein the trigger signal is generated when an arc fault is detected.
