Abstract

The invention relates to a selective trip-free release and signalling method and device for switch-disconnectors of average voltage overhead systems which employ electric signals transmitted across the cables of said system, carrying information on open / closed status of each disconnector, both by the moment when they are emitted in relation to a reference moment, that is the moment when the line is disconnected, and by the polarity of the first alternation, the signals being transmitted between some trip-free release and signalling units (DAS) attached to the system disconnectors and the reception, remote control and testing unit (DRTT) of the transformer substation to allow the triggering only of the disconnector located in the close vicinity of the fault in case of line short-circuit on one hand, and, on the other hand, to allow the remote control of any disconnector from the transformer substation and also to allow the checking of the status of each system disconnector from the transformer substation.
