Recording and event capabilities overview
11. Condition monitoring
The condition monitoring functions of the relay constantly
monitor the performance and the condition of the circuit
breaker. The monitoring comprises the spring charging time,
SF6 gas pressure, the travel time and the inactivity time of the
circuit breaker.
The monitoring functions provide operational circuit breaker
history data, which can be used for scheduling preventive
circuit breaker maintenance.
In addition, the relay includes a runtime counter for monitoring
of how many hours a protected device has been in operation
thus enabling scheduling of time-based preventive
maintenance of the device.
12. Trip-circuit supervision
The trip-circuit supervision continuously monitors the
availability and operability of the trip circuit. It provides open-
circuit monitoring both when the circuit breaker is in its closed
and in its open position. It also detects loss of circuit-breaker
control voltage.
13. Self-supervision
The relay’s built-in self-supervision system continuously
monitors the state of the relay hardware and the operation of
the relay software. Any fault or malfunction detected is used for
alerting the operator.
A permanent relay fault blocks the protection functions to
prevent incorrect operation.
