ARC DETECTION USING CURRENT VARIATION

In an electric circuit supplying AC line current to a load (30,31) from an AC source (26) of given frequency providing repetitive cycles, arc detection is provided by sensing cycle to cycle changes in the AC line current. The AC line current is sampled with a harmonic notch filter (72) at a pluralit...
