Operation
The operation of Disturbance report function DRPRDRE has to be set
Disabled is selected, note that no disturbance report is registered, and none sub-function will
operate (the only general parameter that influences Sequential of events (SOE)).
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 for example 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).
16.6.4.1 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).
Operation in test mode
If the IED is in test mode and
any recordings and no LED information is displayed.
If the IED is in test mode and
mode and the status is indicated in the saved recording.
Post Retrigger
Disturbance report function does not automatically respond to any new trig condition during a
recording, after all signals set as trigger signals have been reset. However, under certain
circumstances the fault condition may reoccur during the post-fault recording, for instance by
automatic reclosing to a still faulty power line.

Application manual
To be able to delete disturbance records,
The IED flash disk should not be used to store any user files. This causes lack of
space for new disturbance recordings.
