A method for detecting and locating a ground failure in an electrical line, of the type comprising a plurality of electrical loads connected to an electrical line (L) and supplied by a supply and control apparatus ( 1 ), each electrical load consisting of a load element and an auxiliary device, electrically connected to each other, with said method providing for: the transmission, over the electrical line (L), of at least a first control signal ((S(i,i+1))) from a first auxiliary device (D<SUB>i</SUB>), associated to a corresponding first load (C<SUB>i</SUB>) belonging to the plurality of electrical loads, to a second auxiliary device ((Di+1)), associated to a corresponding second load ((Ci+1)), adjacent the first load (C<SUB>i</SUB>), belonging to the plurality of electrical loads; the reception of the first control signal ((S(i,i+1))), transmitted by the first auxiliary device (D<SUB>i</SUB>), by the second auxiliary device ((Di+1)); the transmission of a first information signal (Inf(i+1,i)) to the supply and control apparatus ( 1 ) by the second auxiliary device ((Di+1)).
