Currently, almost all medium voltage cable lines (MV) operate with the return wires earthed at both ends of the cable. Such a way of operation causes that during normal states of operation as well as during disturbances, e.g. short-circuits, in the return wires induce currents whose values mainly depend on the currents flowing in the phase wires. These currents in normal operating states are a source of additional energy losses incurred in the MV cables. The effect can be decreased by the return wires cross-bonding or the phase wires transposition. The paper discusses the potential effects that can be achieved by use of the return wires cross-bonding or the phase wires transposition in the domestic grids.
