Modelowanie linii kablowych SN i WN

Abstract

Overhead and cable lines are fundamental elements of power systems. Participation of cable lines is smaller and their percentage decreases as voltage is increased. HV cable lines are often built with the use of cables which are composed of coaxial metallic sheaths. Such cables are also often used in MV networks. The sheath may operate in different confgurations. In the case of Polish MV network the sheaths are earthed at both ends. However, in case of HV cable lines different systems are applied and their confguration should be justifed by model analysis in each individual case.
