Abstract:
A testing device for detecting and locating an arcing fault in an electrical system having a plurality of electrical conductors, said arcing fault having a plurality of characteristics, said testing device comprising:means for locating the electrical conductors of said electrical system; means for detecting at least one of the characteristics of said arcing fault proximate one of said electrical conductors and outputting a responsive signal; and means for annunciating said responsive signal when said means for detecting is proximate said arcing fault; and wherein said means for locating the electrical conductors comprises means for generating a signal having a frequency in said electrical conductors, means for detecting said signal having the frequency proximate one of said electrical conductors and outputting a second responsive signal; and means for annunciating said second responsive signal when said means for detecting said signal having the frequency is proximate said one of said electrical conductors.
