Monitoring
Post Retrigger
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 (
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 (
the post-fault (
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.
14.6.3.2
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 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.
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.
Info103N : Information number (0-255) for binary input N according to IEC-60870-5-103, that is,
69-71: Trip L1-L3, 78-83: Zone 1-6.
See also description in the chapter IEC 60870-5-103.
14.6.3.3
Analog input signals
Up to 40 analog signals can be selected among internal analog and analog input signals.
PCM600 is used to configure the signals.
The analog trigger of Disturbance report is not affected if analog input M is to be included in
the disturbance recording or not (
OperationM = Off , no waveform (samples) will be recorded and reported in graph. However,
If
Trip value, pre-fault and fault value will be recorded and reported. The input channel can still be

OperationM = On , waveform (samples) will also be recorded and reported in graph.
