If, after a few voltage halfwaves have been transmitted, a voltage half-wave is faded out from a time t 0 , the existing currents I are not zero at this time because of the phase offset between current and voltage.

However, the amount of decaying voltage in the time window t 1 , t 2 has fallen below the magnitude of the threshold voltage, so that the hidden mains half-wave is recognized as such.

    un réseau de conducteurs (N, L1, L2, L3 ; L, L1*, L2*, L3*) qui peut être alimenté à la tension de service par le dispositif d'alimentation de puissance (3),
    des consommateurs (4), raccordés au réseau de conducteurs (N, L1, L2, L3 ; L, L1 *, L2*, L3*) et qui peuvent être alimentés par ce réseau à la puissance de service,
    un module-maítre (5) qui permet de moduler la tension alternative délivrée par le dispositif d'alimentation (3) de manière à transmettre, pendant les pauses de service au cours desquelles tous les consommateurs (4) sont coupés, l'information de commutation,
    caractérisée en ce que le module-maítre (5) contient un modulateur (23) qui pour la transmission d'informations binaires diminue ou amène à zéro l'amplitude d'un nombre impair de demi-ondes de tension pour obtenir un signal caractérisant une des valeurs binaires et qui, pour coder l'autre valeur binaire, émet un nombre de demi-ondes de tension modifiées à une autre valeur ou laissées inchangées, le nombre de ces demi-ondes dépassant d'une unité le nombre impair de l'autre valeur binaire et le modulateur, après une ou plusieurs demi-ondes modifiées, produit un nombre pair de demi-ondes non modifiées en tant que périodes de remplissage ne contenant pas d'information, et il existe des modules esclaves (12) qui sont associés aux consommateurs (4) et peuvent chacun être commandés et/ou être programmés par des informations de commutation émises par le module-maítre.
  8. Installation selon la revendication 7, caractérisée en ce que
    le module-maítre (5) est relié à un réseau d'alimentation à une ou plusieurs phases ainsi qu'au module-esclave (12) par l'intermédiaire du réseau de transmission de puissance,
    le module-maítre (5) présente une ou plusieurs unités de calcul (15), au moins un capteur de lumière (14), des capteurs de tension et/ou d'intensité (17, 18) et/ou au moins un élément de puissance (23) formant un modulateur,
    les modules-esclaves (12) comprennent chacun au moins une unité de calcul (31) qui est alimentée en tension alternative de service par l'intermédiaire d'un module de distribution de tension et qui est relié à une horloge en temps réel.
  9. Installation selon la revendication 7, caractérisée en ce que la tension alternative délivrée par le dispositif d'alimentation de puissance (3) est une tension alternative polyphasée et le module-maítre (5) module toutes les phases de la tension alternative polyphasée avec la même information.
  10. Installation selon la revendication 7, caractérisée en ce que l'information de commutation contient au moins un instant d'enclenchement et chaque module-esclave présente un dispositif interne de commutation pour commuter l'utilisateur (4) à l'instant programmé, ce module, après programmation effectuée du consommateur (4) ou après réception d'un ordre de libération, est avantageusement bloqué de manière à ne pas pouvoir recevoir d'autres informations.
  11. Installation selon la revendication 7, caractérisée en ce que le module-maítre (5) contient un dispositif (15) de production d'un signal qui décrit la luminosité naturelle à attendre en fonction de la période de l'année et/ou de l'instant du jour, le module-maítre (12) contient un dispositif de mémorisation dans lequel peuvent être lues des informations concernant le besoin de lumière au niveau des différents consommateurs et le module-maítre (5) présente au moins un capteur (14) pour capter les conditions actuelles.
