Realistic Cable Modeling for Low-Voltage Installations

Numerical models of electrical cables are important to describe accurately signal propagation in electrical networks. We are interested in the modeling of cables used in low-voltage electrical networks. We observed that numerical cable models exhibit unrealistically sharp resonances and antiresonances. We propose an approach to generate cable models with realistic resonances and antiresonances by modifying the attenuation constant. The proposed approach is validated with Vector Network Analyzer (VNA) measurements performed on SPT-2 cable specimens of different lengths.
