Section 17
Monitoring
OperationM = Disabled , no waveform (samples) will be recorded and reported in graph.
If
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.
OperationM = Enabled , waveform (samples) will also be recorded and reported in graph.
If
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 (
OverTrigLeM , UnderTrigLeM : Over or under trig level, Trig high/low level relative nominal value for
analog input M in percent of nominal value.
17.6.3.4 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 (
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 ( Enabled ) or not
Disabled ).
(
OperationM = Disabled , no waveform (samples) will be recorded and reported in graph.
If
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.
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).
Sequential of events
function has no dedicated parameters.
