Abstract
An electric arc detection device samples first, second and third filterings of a signal in a current window and in another window. A correlation is determined between first filtering samples of the current and the other window, a correlation is determined between second filtering samples of the current and the other window, and a correlation is determined between third filtering samples of the current window and the other window. An arc is then detected as a function of the correlations.
