Recording times
M12179-88 v5
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 (
PreFaultRecT
) is the recording time before the starting
point of the disturbance. The setting should be at least
0.1
s to ensure enough
samples for the estimation of pre-fault values in the Trip value recorder (TVR)
function.
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.
15.6.3.2
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.
