Removal of a single line to ground fault by isolating only the faulted phase frequently leads to the creation of a secondary fault arc. Auto reclose protection schemes depend upon the absence of a secondary arc prior to reclosing. Consequently, there is great benefit from a technology to determine secondary arc extinction detection. The testing of SAED can be difficult and require the expense and complexity of staged system faults. A great deal of planning is necessary to do this however, and many fault scenarios cannot be fully studied. Accurate simulation of the phenomenon can alleviate many of these difficulties.
