ELECTRIC ARC DETECTION METHOD AND DEVICE

The invention relates to an electric arc detection method and device in which: samples of first, second and third filterings are determined, in parallel, for a signal for a current time window and for another time window, a correlation is determined among: a first correlation between said samples re...

Summary:The invention relates to an electric arc detection method and device in which: samples of first, second and third filterings are determined, in parallel, for a signal for a current time window and for another time window, a correlation is determined among: a first correlation between said samples resulting from the first filtering and determined for the current window and samples resulting from the first filtering and determined for the other window; a second correlation between said samples resulting from the second filtering and determined for the current window and samples resulting from the second filtering and determined for the other window; a third correlation between said samples resulting from the third filtering and determined for the current window and samples resulting from the third filtering and determined for the other window; and an electric arc is detected as a function of at least said determined correlation.
