Determining wave propagation characteristics of MV XLPE power cable using time domain reflectometry technique

摘要

In this paper, the wave propagation characteristics of single-phase medium voltage (MV) cross-linked polyethylene (XLPE) power cable are determined using Time Domain Reflectometry (TDR) measurement technique. TDR delivers the complex propagation constant (attenuation and phase constant) of lossy cable transmission line as a function of frequency. The frequency-dependent propagation velocity is also determined from the TDR measurements through the parameters extraction procedure. The measurement results can be used to localize the discontinuities as well as the design of communication through distribution power cables.
