Pls see below regarding circuit breakers. Have looked this term up even in IEC but found nothing so help much appreciated thanks
Discordance de phase et de pôle
Le fonctionnement des circuits de discordance de phase "A" et "B" doit être vérifié en simulant une discordance pour chacune des trois phases.
Les déclencheurs chunt d'ouverture "A" et les déclencheurs shunt d'ouverture "B" doivent être activés après le temps fixé par la temporisation de discordance de phase.
Valider le maintien des alarmes et le rappel du verrouillage doit être effectué.
Le fonctionnement des circuits de discordance de pôle "A" et "B" doit être vérifié en simulant une discordance pour chacun des pôles des trois phases.
Les déclencheurs shunt d'ouverture "A" et les déclencheurs shunt d'ouverture "B" de la phase concernée doivent être activés après le temps fixé par la temporisation de discordance de pôle.
On doit vérifier le temps d'application de l'ordre d'ouverture sur les déclencheurs shunt d'ouverture et le verrouillage des déclencheurs shunt de fermeture des trois phases.
Valider le maintien des alarmes et le rappel du verrouillage doit être effectué.

phase discordance
The term used when it comes to this kind of equipment:
"... High-voltage transport and interconnecting networks: automatic fast reclosing avoids tripping between two interconnected sources.
In effect, when breakers on an interconnecting line between two networks trip, there is a rapid loss of phase synchronization if this line is the only one interconnecting them. If there is another line running in parallel, it may trip in turn by overloading, which causes a loss of synchronization.
This desynchronization may be avoided, when the faults are temporary, by quickly reclosing the breakers before the phase shift becomes too great.
If the tripped circuit is three-phase, the reclosing time must be very short, on the order of 0.3 seconds. If the reclose time is longer, there is a risk of closing on a phase discordance.
During timing tests, the O-0.3s-CO test verifies the behavior of the circuit breaker in this particular type of operation. ..."

Distance protection relay
SEL-321
Select the SEL-321 Relay for complete distance protection including single-pole tripping and series-compensated lines.
Apply the SEL-321 Relay for primary and/or backup single-or three-pole trip transmission line protection,including series-compensated lines.Use the advanced single-pole tripping logic with phase selection, open-pole interval protection,and phase discordance logic with three-pole trip to protect against excessive single-pole-open events. Select the load-encroachment feature to prevent operation of three-phase elements under high load conditions. Use the time-overcurrent elements to provide current-dependent, time-delayed fault detection along the protected line and backup protection for remote terminals. SEL SEL-321 has six settings groups for maximum protection scheme flexibility, allow application with bus-tie breakers or for remote system reconfiguration.

: Mismatch est correct. Discordance est un faux-ami....

voir des faux-amis partout, même là où il y en a pas ...une façon de procéder comme une autre… ou peut-être pas?// une ref. sur les ondes sonores est plus fiable que des ref. sur les équipements électriques en question? Méthode intéressante...
