Abstract :In this paper, the wave propagation characteristics of single-phase medium voltage insert ignore into journalissuearticles values(MV); cross-linked polyethylene insert ignore into journalissuearticles values(XLPE); power cable are determined using time domain reflectometry insert ignore into journalissuearticles values(TDR); measurement technique. TDR delivers the complex propagation constant insert ignore into journalissuearticles values(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 calibration of the measuring system insert ignore into journalissuearticles values(MS); is carried-out to avoid the effect of multiple reflections on the accuracy of measurements. The results obtained from the measurements can be used to localize the discontinuities as well as the design of communication through distribution power cables.
