3.2.6.19 Other outputs and alarm signal
• Directional overpower operate signal available at binary output PSM PO4.
• Operate signal from differential protection is available at binary output PSM
PO5.
• Combined overfrequency, underfrequency and rate of change of frequency
protection operate signal available at binary output PSM PO6.
• Combined trip circuit supervision and CB monitoring alarm available at binary
output PSM SO3.
All these outputs are available with a settable minimum alarm delay of 80 ms.
3.2.7 Supervision functions
3.2.7.1 Trip circuit supervision TCSSCBR
Two instances of the trip circuit supervision function are used for supervising Master
trip 1 and Master trip 2. The function continuously supervises the trip circuit and
alarms in case of failure. The function block does not perform the supervision itself
but it is used as an aid for configuration. To prevent unwanted alarms, the function is
blocked when any of the protection function's operate signals is active, or when the
circuit breaker is in open position.
The alarms due to trip circuit failure and GCB monitoring functions are combined and
available at LED alarms, and to binary recorder.
3.2.7.2 Fuse failure supervision SEQRFUF
The fuse failure supervision function gives an alarm in case of open secondary circuits
between the voltage transformer and the IED respectively. A set of three phase
currents and voltages, I3P_N and U3P, are connected to the inputs.
A LED alarm is available for secondary circuit failures. The alarm is also recorded by
a disturbance recorder.
3.2.7.3 Circuit-breaker condition monitoring SSCBR
The circuit-breaker condition monitoring function checks for the healthiness of the
circuit breaker. The circuit breaker status is connected to the function via binary
inputs. The function requires also a pressure lockout input and a spring-charged input
to be connected via binary input COM_101.BI12 and COM_101.BI13 respectively.
