The communication system includes transmitting output status bits indicative of a function of the relay directly from one microprocessor-based protective relay in a power system to a second companion microprocessor-based relay. Each relay has transmit and receive modules connected by a communications link, with the transmit and receive modules using the logic output and input bits produced by the respective relays in their respective relay calculations.
Le système de communication de l'invention transmet, d'un premier relais de protection à microprocesseur d'un système d'alimentation à un second relais à microprocesseur connexe, des bits de situation représentant une fonction du premier relais. Chacun de ces relais comporte des modules d'émission et de réception connectés par une liaison de communication, ces modules utilisant les signaux logiques et les bits produits par chacun des relais comme résultats de leurs calculs respectifs.
