Abstract
The present invention provides a method for monitoring a condition of an electrical cable, the method including: providing a reference signal CH0 and a signal CH1, the signal CH1 being the reference signal CH0 after amplitude and phase modulation by a cable impedance ZDUT of the electrical cable; calculating the cable impedance ZDUT as a function of the applied signal frequency based on the reference signal CH0 and the signal CH1; and analyzing the cable impedance providing an assessment of the cable condition. A system performing the method is also disclosed.
