Abstract:
A pulsing apparatus for an electrical system having a nominal voltage and a rated voltage, said pulsing apparatus comprising:first terminals structured to input a first voltage, said first voltage being about said nominal voltage; means for generating a signal from said first voltage, said signal having a duty cycle; means for transforming said first voltage to a second voltage having said duty cycle; second terminals; means for outputting a current at about said second voltage to said second terminals, wherein said second voltage is greater than said first voltage and less than said rated voltage, said second voltage being adapted to identify an arcing fault in said electrical system; wherein said duty cycle limits an average value of said current to less than about 6 mA; and wherein said first terminals are structured to input an alternating current voltage as said first voltage.
