Patent ID: 8924169

Claim:
An electrical arc detection method comprising the steps of: measuring, through use of an electrical parameter measurer, an electrical parameter at a location within a power generation circuit at a non-arc condition time to generate a non-arc condition measured signal; and using at least one microprocessor to: mathematically transform said non-arc condition measured signal to generate a mathematically transformed, non-arc condition signal; identify at least one lower noise region of said mathematically transformed, non-arc condition signal; identify a mathematically transformed, non-arc condition signal value for each of said at least one lower noise region; measure said electrical parameter at said location within said power generation circuit at a later time to generate a later measured signal; mathematically transform said later measured signal to generate a mathematically transformed later signal; determine a value of said mathematically transformed later signal at each of said at least one lower noise region; compare said value of said mathematically transformed later signal at each of said at least one lower noise region with said mathematically transformed, non-arc condition signal value at a respective one of said at least one lower noise region; and make a determination relative to presence of arc within said power generation circuit; reevaluate to determine whether said at least one lower noise region of said mathematically transformed, non-arc condition signal is still lower noise; determine that said at least one lower noise region is no longer lower noise; and update said at least one lower noise region to an updated at least one lower noise region.
