Application manual
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).
Post retrigger (PostRetrig) can be set to Enabled or Disabled. Makes it possible to
choose 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 trip value calculations if installed, in operation and started
Operation in test mode
If the IED is in test mode and OpModeTest = Disabled. Disturbance report function
does not save any recordings and no LED information is displayed.
If the IED is in test mode and OpModeTest = Enabled. Disturbance report function
works in normal mode and the status is indicated in the saved recording.
Binary input signals
Up to 96 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 96 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.
TrigDRN: Disturbance report may trig for binary input N (Enabled) or not (Disabled).
TrigLevelN: Trig on positive (Trig on 1) or negative (Trig on 0) slope for binary input N.
Func103N: Function type number (0-255) for binary input N according to
IEC-60870-5-103, that is, 128: Distance protection, 160: overcurrent protection, 176:
transformer differential protection and 192: line differential protection.
