| titleOfInvention | Method and system for monitoring a condition of electrical cables |
| abstract | A method and a system are described for monitoring a condition of an electrical cable. The method comprises applying a broadband signal wave having a frequency f to a first end of the electrical cable the electrical cable, wherein the broadband signal wave is phase and amplitude modulated by at least a cable impedanceof the electrical cable and acquiring the phase and amplitude modulated broadband signal wave transmitted and reflected by the electrical cable. Signal analyses is performed on the acquiredthe phase and amplitude modulated broadband signal wave. The signal analyses results in establishing a relationship between a real and an imaginary part of a phase impedance spectrum Fourier transform of the power spectrum in an interval around atleast one of the locations x, x 2,...,x n along the cabledue to discontinuities at these locations, and identifying impedance changes in theselocations x, x 2,...,x n along the cable from said real and imaginary part.Analyzing a second order reflectionof the broadband signal in said identified fault locations may establishing a local degradation severity of an identified fault in the cable insulation in at least one of the locations x, x 2,...,x n along the cable. |
