4.1.4
Use of the two positions information
In that case, in the P746 topology, the position will be seen closed only when the isolator will
arrive at the closed position.
This is not recommended as the P746 may trip in 2 steps instead of 1 in case of a fault
appearing during the closing period of the isolator.
4.1.5
Use of the two positions information
In that case, in the P746 topology, the position will be seen closed only when the isolator will
arrive at the closed position and seen open only when the isolator will arrive at the open
position.
This is not recommended as the P746 may trip in 2 steps instead of 1 in case of a fault
appearing during the closing period of the isolator.

Isolator supervision alarm
When using both positions information, an alarm can be raised when the 00 or 11

4.2
Circuit breaker state monitoring
An operator at a remote location requires a reliable indication of the state of the switchgear.
Without an indication that each circuit breaker is either open or closed, the operator has
insufficient information to decide on switching operations. The relay incorporates circuit
breaker state monitoring, giving an indication of the position of the circuit breaker, or, if the
state is unknown, an alarm is raised.
