The list can be configured to show oldest or newest events first with a setting on the localHMI.The sequential of events function runs continuously, in contrast to the event recorderfunction, which is only active during a disturbance, and each event record is an integralpart of its associated DR.The name of the binary signal that appears in the event recording is the user-defined nameassigned when the IED is configured. The same name is used in the disturbance recorderfunction , indications and the event recorder function .The sequential of events is stored and managed separate from the disturbance reportinformation.12.7.5 Technical dataTable 393:DRPRDRE technical dataFunction ValueBuffer capacity Maximum number of events in the list 1000Resolution 1 msAccuracy Depending on timesynchronizing12.8 Trip value recorder12.8.1 FunctionalityInformation about the pre-fault and fault values for currents and voltages are vital for thedisturbance evaluation.The Trip value recorder calculates the values of all selected analog input signals connectedto the Disturbance recorder function. The result is magnitude and phase angle before andduring the fault for each analog input signal.The trip value recorder information is available for the disturbances locally in the IED.The trip value recorder information is an integrated part of the disturbance record(Comtrade file).12.8.2 Function blockThe Trip value recorder has no function block of it’s own.1MRK 511 287-UUS A Section 12Monitoring493Technical manual
