Supervision des TP et TC » Action de la STP sur détection anomalie: » Signalisation = Génération d’une alarme uniquement » Blocage = Verrouillage optionnel des éléments de protection dépendants de la tension + conversion optionnelle des éléments à maximum de courant directionnels en non-directionnels

» Suite à la détection d’une anomalie par STP, le signal de blocage sera maintenu après expiration de la Tempo STP » Mode réinit. STP: L’aquittement du maintien se fait soit manuellement (par la face avant ou la communication) soit automatiquement par rétablissement des 3 tensions phases (3 V > seuil fixe – 30V pour Vn=100/120V)

Note : la STP fonctionne lorsqu’une tension résiduelle est détectée en l’absence de courant inverse. En cas de perte de tension sur les 3 phases, d’autres mécanismes sont mis en place pour détecter une anomalie sur les mesures tension. © ALSTOM 2010. All rights reserved.
