Why does the waveform recorder continue to record new waveforms?

To make the waveform recorder stop recording continuously:

  1. Check which events are configured to trigger the Waveform Recorder (<Device Para/ Recorders / Waveform rec>), e.g. Protection Alarm.
  2. Check within the Event Recorder, which protection function creates the trigger (<Operation/ Recorders / Event rec>).
  3. Check the settings of this protection function. Adapt them, if necessary. Example: Protection function df/dt (ROCOF) is configured too sensitive and is creating alarms with high frequency. Change the settings of this function. Alternatively you can also change the trigger source of the Waveform Recorder. But this is less advisable.
