Monitoring
Operation
The operation of Disturbance report function DRPRDRE has to be set
selected, note that no disturbance report is registered, and none sub-function will operate
(the only general parameter that influences Event list (EL)).
Operation = Off :
• Disturbance reports are not stored.
• LED information (yellow - start, red - trip) is not stored or changed.
Operation = On :
• Disturbance reports are stored, disturbance data can be read from a PC for example using
PCM600.
• LED information (yellow - start, 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

The different recording times for Disturbance report are set (the pre-fault time, post-fault
time, and limit time). These recording times affect all sub-functions more or less but not the
Event list (EL) function.
Prefault recording time (
disturbance.
Postfault recording time (
disappearance of the trig-signal.
Recording time limit (
limits the recording time if some trigging condition (fault-time) is very long or permanently
set.
Operation in test mode
If the IED is in test mode and
any recordings and no LED information is displayed.

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.
