Why link them? Any failure opening one or other breaker is sufficient to stop fault current. The only reason to even have both breakers is so the transformer

Why link them? Any failure opening one or other breaker is sufficient to stop fault current.
The only reason to even have both breakers is so the transformer can be taken out for maintenance.
- caf 2y agoThe idea is to fully disconnect the faulted element from the power system. In particular with transformers, you don't want it backfed from the low voltage side if the high voltage side is isolated.
- raverbashing 2y agoInteresting, makes sense. And yes I think the backfeeding is the problem, you don't want the other generator to start automatically while the other side is still connected
