16.6.3.1 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).
Post retrigger (
performance of Disturbance report function if a new trig signal appears in the post-fault window.
PostRetrig = Disabled
The function is insensitive for new trig signals during post fault time.
PostRetrig = Enabled
The function completes current report and starts a new complete report that is, the latter will
include:
• new pre-fault- and fault-time (which will overlap previous report)
• events and indications might be saved in the previous report too, due to overlap
• new fault locator and trip value calculations if installed, in operation and started
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.
16.6.3.2 Binary input signals
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 352signals, 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.
Application manual
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.
PreFaultRecT ) is the recording time before the starting point of the
PostFaultRecT ) is the maximum recording time after the disappearance
TimeLimit ) is the maximum recording time after trig. The parameter limits
PostRetrig ) can be set to Enabled or Disabled . Makes it possible to choose
