Abstract

Un sistema eléctrico de señalización sobre líneas de transmisión, para la transmisión, por medio de corrientes alternas, de señales que incluyen un número constante de elementos de señalización, usando corrientes alternas de diferentes frecuencias, a saber; una primera corriente alterna (frecuencia f1) para señalar el número constante de elementos de señalización y la duración de cada uno, y una segunda o más, frecuencias alternas (frecuencia f2, f3, etc.) para señalar los elementos de señalización como tales (p.e. apertura o cierre de la corriente).An electrical signaling system on transmission lines, for the transmission, by means of alternating currents, of signals that include a constant number of signaling elements, using alternating currents of different frequencies, namely; a first alternating current (frequency f1) to indicate the constant number of signaling elements and the duration of each one, and a second or more, alternating frequencies (frequency f2, f3, etc.) to signal the signaling elements as such ( eg opening or closing of the current).
