Experimental Evaluation of a Low-Voltage Power Distribution Cable Model Based on a Finite-Element Approach

The authors presented in a former paper, a thorough study concerning the electrical parameters of low-voltage power distribution cables widely used in residential networks in the frequency range up to 100 MHz. The calculation of the electrical parameters was based on a finite-element procedure with respect to the cables´ normal operational conditions. In this paper, a cable model is presented based on the above study. Approximations that are made are analyzed and validated. Moreover, an experimental setup is used to validate the cable model, which includes various and both single-path and multipath cable networks in order to achieve generality. Experimental results are analyzed, and theoretical difficulties based on the cables´ nature are denoted.
