Problem description

Corrective action

The Event Recorder does permanently show new events (<Operation/ Recorders / Event rec>).

To observe this phenomenon in PowerPort- E, please execute a "refresh" (F5 or Ctrl+F5).

Proceed as follows:

1. Look inside the Event Recorder which protection function is creating the events.
2. 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.

The Waveform Recorder shows a high number of created disturbance records. This number is growing steadily over time (<Operation/ Recorders / Waveform rec>).

To observe this phenomenon in PowerPort-E, please execute a "refresh" (F5 or Ctrl+F5).

Check the following issues:

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.
