“…According to the transmission line theory [19], the distribution parameter model can be applied to describe the electrical network structure of power cable under high frequency power source, as illustrated in Figure 1. R0, L0, G0 and C0 represent the equivalent resistance, inductance, conductance and capacitance of power cable in per unit length, respectively, which can be calculated according to the material, size, structure and other parameters of cables [20].…”

Frequency domain reflectometry (FDR) technologies could be applied to locate defects in cables effectively. Owing to the large space span and complex operating environment of the actual XLPE distribution cables, segmented thermal aging phenomenon occurs easily, causing the nonuniform distribution of electrical parameters along cables, which might affect the defect location accuracy ultimately. In this paper, the segmented thermal aging cable models were established and the effect of segmented-aging in XLPE distribution cables on defect location accuracy was explored based on simulation. It was found the floating range of defect location deviation in segmented thermal aging cable models could reach 10% of the whole cable length, which could not be ignored. Further research and analysis revealed that the defect location deviation in the segmented-aging cable mainly attributes to the differences of distributed wave velocities in the cable. On this basis, a correction coefficient of defect location M was put forward for the segmented-aging cable models established, which has achieved remarkable results. Finally, a segmentedaging cable model with a length of 119 m was built in the laboratory, and the validity for improving defect location accuracy by considering the differences of wave velocities was verified through experiments. Results show the defect location deviation can be reduced from 2.19% to 0.39% by introducing M.

“…Several articles presented active FSSs, among which only very few has a tunable passband [12][13][14][15], and most of them have a switchable passband [16][17][18][19][20]. Some multifunctional active FSSs are also proposed by using PIN diodes in recent years [21,22].…”

In this study, a frequency-selective rasorber with a tunable passband and two absorptive bands is presented. It is designed using two active FSSs, an absorptive FSS realized with tripole elements, and a lossless bandpass FSS achieved with ring slots. Both active FSSs embedded with varactors realize the shift of transmission frequency bands by controlling the bias voltage of the feed network. The working principle is briefly investigated according to an equivalent circuit model. A prototype is fabricated and measured to verify the simulated results, which show that a passband is tuned from 3 to 4.78 GHz between two absorptive bands, and the maximum band of |S11| < −10 dB covers from 2.2 to 7.96 GHz.
