Theory and Simulation of Coaxial Cable Soft Fault Detection Based on Integral Transform Model

In the process of practical application, coaxial cable is prone to soft faults such as wear. In this paper, the influence of faulty cable on impedance spectrum is analyzed by using the transmission line model of coaxial cable and the frequency characteristics of distributed parameters. Using impedance spectrum and propagation coefficient, based on integral transformation, the soft fault detection model of coaxial cable is theoretically analyzed, and the fault location diagnosis model is established. Then ADS software is used to simulate the fault detection model. The simulation results are good and the error is small. Finally, combined with the simulation steps, some suggestions for practical engineering application are given.
