telealimentazione a line transmission cables subjected to the influence of internal electric fields

摘要

The invention relates in particular to remote supply with AC of repeaters of a transmission line with symmetrical pairs. It provides a remote supply system in which the AC remote supply passes through a loop formed by two pairs of the line and in which each repeater is supplied by the secondary winding of a current transformer whose primary winding is formed by two identical windings inserted in series opposition, one in one of the pairs forming the remote supply loop, the other in the other of these pairs. It applies advantageously to the transmission lines which have a path common to an electric power line as is the case for example with a transmission line along electrified railway lines.
