Postfault recording time (PostFaultRecT) is the maximum recording time after thedisappearance of the trig-signal (does not influence the Trip value recorder (TVR)function).Recording time limit (TimeLimit) is the maximum recording time after trig. Theparameter limits the recording time if some trigging condition (fault-time) is verylong or permanently set (does not influence the Trip value recorder (TVR)function).Operation in test mode M12179-492 v4If the IED is in test mode and OpModeTest = Off. Disturbance report function doesnot save any recordings and no LED information is displayed.If the IED is in test mode and OpModeTest = On. Disturbance report functionworks in normal mode and the status is indicated in the saved recording.Post Retrigger M12155-173 v7Disturbance report function does not automatically respond to any new trigcondition during a recording, after all signals set as trigger signals have been reset.However, under certain circumstances the fault condition may reoccur during thepost-fault recording, for instance by automatic reclosing to a still faulty power line.In order to capture the new disturbance it is possible to allow retriggering(PostRetrig = On) during the post-fault time. In this case a new, complete recordingwill start and, during a period, run in parallel with the initial recording.When the retrig parameter is disabled (PostRetrig = Off), a new recording will notstart until the post-fault (PostFaultrecT or TimeLimit) period is terminated. If a newtrig occurs during the post-fault period and lasts longer than the proceedingrecording a new complete recording will be started.Disturbance report function can handle a maximum of 3 simultaneous disturbancerecordings.15.6.3.2 Binary input signals M12179-90 v9Up to 352 binary signals can be selected among internal logical and binary inputsignals. The configuration tool is used to configure the signals.For each of the 352 signals, it is also possible to select if the signal is to be used asa trigger for the start of the Disturbance report and if the trigger should be activatedon positive (1) or negative (0) slope.OperationN: Disturbance report may trig for binary input N (On) or not (Off).TrigLevelN: Trig on positive (Trig on 1) or negative (Trig on 0) slope for binaryinput N.Section 15 1MRK 505 393-UEN BMonitoring340 Line differential protection RED650 2.2 IECApplication manual
