Section 16
Monitoring
In order to capture the new disturbance it is possible to allow retriggering (PostRetrig = Enabled) during
the post-fault time. In this case a new, complete recording will pickup and, during a period, run in parallel
with the initial recording.
When the retrig parameter is disabled (PostRetrig = Disabled), a new recording will not pickup 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.
16.6.4.2

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.
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.
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.
16.6.4.3

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 = Enabled/Disabled).
If OperationM = Disabled, no waveform (samples) will be recorded and reported in graph. However, Trip
value, pre-fault and fault value will be recorded and reported. The input channel can still be used to trig
the disturbance recorder.
If OperationM = Enabled, waveform (samples) will also be recorded and reported in graph.
NomValueM: Nominal value for input M.
OverTrigOpM, UnderTrigOpM: Over or Under trig operation, Disturbance report may trig for high/low level
of analog input M (Enabled) or not (Disabled).
OverTrigLeM, UnderTrigLeM: Over or under trig level, Trig high/low level relative nominal value for
analog input M in percent of nominal value.

Sub-function parameters

All functions are in operation as long as Disturbance report is in operation.
