ABSTRACT:
A method of and apparatus for automatically isolating a faulty section of a power line, of an electrical supply network, the power line being adapted to be connected to at least one energy source and to be temporarily divided up into sections by switches following the appearance of an excess current, and automatically reconnecting normally operating sections of the power line to at least one energy source, wherein a signal is transmitted from the place of at least one switch, which has opened automatically after an excess current that has passed through it, through a non-faulty part of the power line to at least one other switch, through which at least a part of the excess current had passed to the now opened switch, and which has automatically opened as well, reception of the aforementioned signal being an essential requirement for closing the said other switch.
