Arc Mitigation Techniques EC&M. The high-resistance device will limit the fault current to a low value (i.e., 5A or 10A), as opposed to tens of thousands of amperes. This will impede the progress of the arc, and the fault will remain as a single phase-to-ground fault instead of propagating into a Q.
