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 MiCOM
P120/P121/P122/P123 relays incorporate a circuit breaker state monitoring, giving an
indication of the position of the circuit breaker.
This indication is available either on the relay front panel (P122 - P123 only) or via the
communication network.
The positions of the CB can be selected under the
AUTOMAT.CTRL/Inputs
and
CONFIGURATION/Led
menu.
Further, the MiCOM P122 and P123 relays are able to inform the operator that the CB has
not opened following a remote trip command (refer section “CB FAIL protection”).
