Postfault recording time ( PostFaultRecT ) is the maximum recording time after the
disappearance of the trig-signal (does not influence the Trip value recorder (TVR)
function).
Recording time limit ( TimeLimit ) is the maximum recording time after trig. The
parameter limits 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
M12179-492 v4
If the IED is in test mode and OpModeTest = Off . Disturbance report function does
not save any recordings and no LED information is displayed.
If the IED is in test mode and OpModeTest = On . Disturbance report function
works in normal mode and the status is indicated in the saved recording.
Post Retrigger
M12155-173 v7
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.
In order to capture the new disturbance it is possible to allow retriggering
(
PostRetrig = On ) during the post-fault time. In this case a new, complete recording
will start and, during a period, run in parallel with the initial recording.
When the retrig parameter is disabled ( PostRetrig = Off ), a new recording will not
start until the post-fault ( PostFaultrecT or TimeLimit ) period is terminated. If a new
trig occurs during the post-fault period and lasts longer than the proceeding
recording a new complete recording will be started.
Disturbance report function can handle a maximum of 3 simultaneous disturbance
recordings.
18.6.3.2 Binary input signals
M12179-90 v9
Up to 352 binary signals can be selected among internal logical and binary input
signals. The configuration tool is used to configure the signals.
For each of the 352 signals, it is also possible to select if the signal is to be used as
a trigger for the start of the Disturbance report and if the trigger should be activated
on positive (1) or negative (0) slope.
OperationN : Disturbance report may trig for binary input N ( On ) or not ( Off ).
TrigLevelN : Trig on positive ( Trig on 1 ) or negative ( Trig on 0 ) slope for binary
input N.
