Abstract

1. Procedimiento para activar de una forma selectiva una pluralidad de cargas eléctricas en instantes relativos predeterminados, respectivamente correspondientes, caracterizado porque comprende las fases de: generar señales de temporización de referencia en un lugar central; recibir y elaborar por separado las señales de temporización de referencia en el lugar de cada carga eléctrica; comprendiendo la fase de elaboración en cada lugar la medición de un intervalo de tiempo de referencia respectivamente correspondiente definido por las señales de temporización de referencia y medir ulteriormente un retardo correspondientemente predeterminado en función al intervalo de tiempo de referencia medido anteriormente; y activar cada carga eléctrica después de haber transcurrido el retardo predeterminado correspondiente.
