Abstract (en)
[origin: FR2791170A1] The invention concerns a method which consists in: providing around the electric transmission line connection a coil (20); powering the coil with alternating current; moving the coil; measuring the coil impedance and comparing the measured impedance to a reference impedance, The coil (20) is preferably interrupted by a slot (21) for engaging the coil (20) around the cable linked to a connector of the connection.
