Locating cable faults is of significant importance


for the stable operation of the power system. Currently,


mainstream methods like partial discharge testing and time-


domain reflectometry impact by issues like filtering distortions


and rapid attenuation of high-frequency signals, making it


difficult to accurately locate high-resistance cable faults. This


paper introduces a three-dimensional wideband impedance


localization method based on temperature gradients. The paper


provides a theoretical analysis of impedance at cable joints and


conducts experiments on a 57-meter cross-linked polyethylene


medium-voltage cable, the experimental results demonstrates the


effectiveness of the proposed three-dimensional wideband


impedance method.
