Abstract:
An advanced model of the power medium voltage cable for high frequency is created. Simulations of the cable model in frequency domain are made. The distributions of the impedance in frequency of the power cable by different length in border mode - opening circuit and short circuit are obtained. The change of the impedance in frequency domain depends of mode of power cable. Resonance impedance has an importance miscellaneous for low and high frequency. The resonance frequencies of power cables with different length are determined. The models are validated in the time domain by investigation of transient simulations for cables with different length when they are switched into the electric energy sources with high frequency.
