It facilitates understanding system behaviorand related primary and secondary equipment during and after a disturbance.Recorded information is used for different purposes in the short perspective (forexample corrective actions) and long perspective (for example functional analysis).The Disturbance recorder acquires sampled data from selected analog- and binarysignals connected to the Disturbance recorder function (maximum 40 analog and 96binary signals). The binary signals available are the same as for the event recorderfunction.The function is characterized by great flexibility and is not dependent on the operationof protection functions. It can record disturbances not detected by protectionfunctions. Up to 9,9 seconds of data before the trigger instant can be saved in thedisturbance file.The disturbance recorder information for up to 100 disturbances are saved in the IEDand the local HMI is used to view the list of recordings.14.9.2 Function blockThe Disturbance recorder has no function block of it’s own.14.9.3 SignalsSee Disturbance report for input and output signals.14.9.4 SettingsSee Disturbance report for settings.1MRK 502 048-UEN A Section 14Monitoring541Technical manual
