Abstract

The construction of the metallic screen or other power cable elements designed for the short-circuit current conducting has significant influence on the cost of medium voltage cables in PVC (polyvinyl chloride) or XLPE (cross-linked polyethylene) insulation. Not only the price of the cable, but also the technical criteria must be taken into consideration while choosing the types of cables and the cross-section of the metallic screen or similar elements. These technical criteria can be based on the double line-to-ground faults statistical analysis in the network. The paper presents the description of the rules of carrying out such analyses in urban cable MV network as well as the sample results of computer simulations. The method of the double line-to-ground fault currents calculation is consistent with the international standard
