Functional module diagram for calculating inactive days and alarm for
circuit breaker operation monitoring
Inactivity timer
The module calculates the number of days the circuit breaker has remained inactive,
that is, has stayed in the same open or closed state. The calculation is done by
monitoring the states of the
POSOPEN
and
POSCLOSE
auxiliary contacts.
The inactive days
NOOPRDAY
is available through the Monitored data view. It is also
possible to set the initial inactive days by using the
InactDayInit
parameter.
Alarm limit check
When the inactive days exceed the limit value defined with the
InactDayAlm
setting,
the
NOOPRALM
alarm is initiated. The time in hours at which this alarm is activated
can be set with the
InactHourAlm
parameter as coordinates of UTC. The alarm signal
NOOPRALM
can be blocked by activating the binary input
BLOCK
.

Breaker contact travel time
The breaker contact travel time module calculates the breaker contact travel time for
the closing and opening operation. The operation of the breaker contact travel time
measurement can be described by using a module diagram. All the modules in the
diagram are explained in the next sections.
