Abstract:
A method for testing a conductor element applicable to locating a continuity defect of the conductor element, the conductor element having, relative to a reference conductor, an insulation resistance and a leak capacitance spread along the conductor element, the method comprising:a step of injecting into the conductor element at least two currents of different frequencies by means of a current or voltage generator, one terminal of which is connected to the reference conductor, a plurality of steps of measuring the amplitudes of currents at various measuring points chosen along the conductor element, and a plurality of steps of calculating, after each measurement, the imaginary part of at least one of the currents and/or the downstream leak capacitance of the conductor element, an electrical continuity defect of the conductor element being located when the imaginary part calculated and/or the downstream leak capacitance proves to be zero before the end of the conductor element is reached.
