Monitoring
Operation = Disabled :
•
Disturbance reports are not stored.
•
LED information (yellow - pickup, red - trip) is not stored or changed.
Operation = Enabled :
•
Disturbance reports are stored, disturbance data can be read from the local HMI and from a
PC using PCM600.
•
LED information (yellow - pickup, red - trip) is stored.
Every recording will get a number (0 to 999) which is used as identifier (local HMI, disturbance
handling tool and IEC 61850). An alternative recording identification is date, time and sequence
number. The sequence number is automatically increased by one for each new recording and is
reset to zero at midnight. The maximum number of recordings stored in the IED is 100. The oldest
recording will be overwritten when a new recording arrives (FIFO).

Recording times
Prefault recording time (
disturbance. The setting should be at least
pre-fault values in the Trip value recorder (TVR) function.
Postfault recording time (
of the trig-signal (does not influence the Trip value recorder (TVR) function).
Recording time limit (
the recording time if some trigging condition (fault-time) is very long or permanently set (does
not influence the Trip value recorder (TVR) function).
Post retrigger (
performance of Disturbance report function if a new trig signal appears in the post-fault window.
PostRetrig = Disabled
The function is insensitive for new trig signals during post fault time.
PostRetrig = Enabled

To be able to delete disturbance records,
The maximum number of recordings depend on each recordings total recording
time. Long recording time will reduce the number of recordings to less than 100.
The IED flash disk should NOT be used to store any user files. This might cause
disturbance recordings to be deleted due to lack of disk space.
PreFaultRecT ) is the recording time before the starting point of the
PostFaultRecT ) is the maximum recording time after the disappearance
TimeLimit ) is the maximum recording time after trig. The parameter limits
