can be triggered by the start or the trip signal of a protection
block, or by both. The available measurement modes include
DFT, RMS and peak-to-peak. Fault records store relay

Recording and event capabilities overview

12. 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.

13. 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.
