This paper proposes a methodology to improvement of the power supply continuity indexes. This methodology c onsists in the fast fault location through hybrid system ba sed on artificial intelligence. The proposed hybrid system combine a fault location algorithm (Ratan Das) and a classi fication technique (Support Vectorial Machine, Finite Mixtur e and LAMDA technique), these techniques combined with th e fault location algorithm allow to identify the typ e and location of the faults.
