IfOperationM =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 beused to trig the disturbance recorder.IfOperationM =On, waveform (samples) will also be recorded and reported in graph.Event recorder M12179-444 v4Event recorder (ER) function has no dedicated parameters.Trip value recorder M12179-442 v3ZeroAngleRef: The parameter defines which analog signal that will be used as phase anglereference for all other analog input signals. This signal will also be used for frequencymeasurement and the measured frequency is used when calculating trip values. It is suggestedto point out a sampled voltage input signal, for example, a line or busbar phase voltage(channel 1-30).Event list M12179-440 v3Event list (EL) (SOE) function has no dedicated parameters.12.5.3.5 Consideration M12179-420 v5The density of recording equipment in power systems is increasing, since the number ofmodern IEDs, where recorders are included, is increasing. This leads to a vast number ofrecordings at every single disturbance and a lot of information has to be handled if therecording functions do not have proper settings. The goal is to optimize the settings in eachIED to be able to capture just valuable disturbances and to maximize the number that ispossible to save in the IED.The recording time should not be longer than necessary (PostFaultrecT andTimeLimit).• Should the function record faults only for the protected object or cover more?• How long is the longest expected fault clearing time?• Is it necessary to include reclosure in the recording or should a persistent fault generate asecond recording (PostRetrig)?Minimize the number of recordings:• Binary signals: Use only relevant signals to start the recording that is, protection trip,carrier receive and/or start signals.• Analog signals: The level triggering should be used with great care, since unfortunatesettings will cause enormously number of recordings. If nevertheless analog inputtriggering is used, chose settings by a sufficient margin from normal operation values.Phase voltages are not recommended for trigging.Remember that values of parameters set elsewhere are linked to the information on a report.Such parameters are, for example, station and object identifiers, CT and VT ratios.12.6 Logical signal status report BINSTATREP GUID-E7A2DB38-DD96-4296-B3D5-EB7FBE77CE07 v212.6.1 Identification GUID-E0247779-27A2-4E6C-A6DD-D4C31516CA5C v3Function description IEC 61850identificationIEC 60617identificationANSI/IEEE C37.2device numberLogical signal status report BINSTATREP - -Section 12 1MRK 505 355-UEN AMonitoring218Application manual
