Application manual
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 red 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.
Setting information
SetInfoInDrep: Parameter used to enable or disable the settings information in
disturbance header.
Event recorder
Event recorder (ER) 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 (EL) (SOE) 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 handled if the recording functions do not have proper settings. The goal is to
optimize the settings in each IED to be able to capture just valuable disturbances
and to maximize the number that is possible to save in the IED.
The recording time should not be longer than necessary (PostFaultrecT and
TimeLimit).
