Parameter: Fault recording
•
Recommended setting value (_:2761:130) Fault recording = with pickup
With the Fault recording parameter, you define the time interval at which faults are recorded. The total
record duration is defined as the duration of the fault plus the total of the parameters Pre-trigger time,
Post-trigger time and is limited by the maximum record duration.

Description
The fault recording time is determined by the total number of all protection
pickups. The resulting pickup signals of all function groups are taken into
account.
Note: When the post-trigger time has expired, the indications of an auto-
matic reclosing function are not recorded. Evolving faults after expiry of the
post-trigger time can result in the opening of a new fault with its own
recording.
The fault recording time is determined by the total number of all protection
pickups including short and long interruptions (automatic reclosing cycles).
It includes the resulting pickup signals of all function groups and the
runtimes of initiated automatic reclosing cycles for all active automatic
reclosing functions.
The fault recording time is defined user-specific.
Note: You must specify all signals for individual definition of the fault
recording time in the DIGSI 5 information-routing matrix. In the information
routing matrix in the Fault record column, the fault recording has for this
purpose a separate column Trigger. The record duration is calculated from
the logical OR operation of all initiated, configured signals.
Description
Delete all recording via the function key. The
error numbers are reset.
Delete all recording via the function key. The
error numbers remain as is.
Start recording by an external binary signal, for
example, by the trip command of an external
protection device. The set pre and post-trigger
time are taken into account.
Start a recording of fixed duration (parameter
Manual record time ) by way of an
external binary signal, for example, manually via
the function key or by an external binary signal.
Description
Status feedback of the fault recording according
to chapter 2.3 Function Control
The indication of the current error number
allows a unique allocation of entries in the
message buffers for the recorded fault records.
