Method for locating an insulation fault (Rd) in the screen (SCR) of a cable relative to the ground, the screen being electrically accessible at least at one point of origin (Po) and at one terminal point (Pe). A current is injected between the point of origin (Po) and the terminal point (Pe) of the screen (SCR), by a current or voltage generator (21) that is insulated from the ground, a first electric voltage (U1) is measured at the point of origin (Po), in reference to the ground, and a second electric voltage (U, U2) is measured at the terminal point (Pe). The ratio between the first (U1) and the second (U, U2) voltages measured is representative of the relative position (Pdr) of the insulation fault between the point of origin (Po) and the terminal point (Pe).
