Abstract
A fault location system in a cable transport installation comprises a safety unit (10) and an end module (13) connected by an electrical safety line (11). The safety line (11) comprises a plurality of cable fault contacts (14) of the normally-closed type connected in series. The location system includes a plurality of location modules (20) distributed along the transport installation, each of which comprising a first test contact (21), of the normally-open type, for short-circuiting the safety line (11). Once a fault coming from one of the cable fault contacts (14) is detected, each location module (20) is capable of selectively closing its first test contact (21) so as to be able to locate said faulty contact (14) on the safety line.
