PROBLEM TO BE SOLVED: To provide an improved arc flash prevention mechanism that has an improved response time and high cost efficiency.SOLUTION: There is provided an arc mitigating device (110), including a first plasma generation device (136) and a second plasma generation device (138). The second plasma generation device includes a pair of opposing and spaced apart electrodes (144a, 144b) and a low voltage, high current energy source (148) connected therebetween. A conduit (194) is configured to direct plasma between the first and second plasma generation devices, such that the second plasma generation device receives plasma generated by the first plasma generation. The plasma from the first plasma generation device acts to reduce the impedance of an area between the pair of opposing electrodes sufficiently to allow an arc to be established therebetween due to the low voltage, high current energy source. |
