Application manual
If OperationM = On, 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 (On) or not (Off).
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.
Indications
IndicationMaN: Indication mask for binary input N. If set (Show), a status change of
that particular input, will be fetched and shown in the disturbance summary on local
HMI. If not set (Hide), status change will not be indicated.
SetLEDN: Set yellow Start and red Trip LED on local HMI in front of the IED if binary
input N changes status.
Disturbance recorder
OperationM: Analog channel M is to be recorded by the disturbance recorder (On) or
not (Off).
If OperationM = Off, 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 = On, waveform (samples) will also be recorded and reported in graph.
Event recorder
Event recorder function has no dedicated parameters.
Trip value recorder
ZeroAngleRef: The parameter defines which analog signal that will be used as phase
angle reference for all other analog input signals. This signal will also be used for
frequency measurement and the measured frequency is used when calculating trip
values. It is suggested to point out a sampled voltage input signal, for example, a line
or busbar phase voltage (channel 1-30).
Event list
Event list function has no dedicated parameters.

Consideration

The density of recording equipment in power systems is increasing, since the number
of modern IEDs, where recorders are included, is increasing. This leads to a vast
number of recordings at every single disturbance and a lot of information has to be
