Problem Description
Corrective Action
The Event Recorder is permanently logging
new events.
The Event Recorder does permanently show
new events (<Operation/ Recorders / Event
rec>).
To observe this phenomenon in Smart view,
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 Disturbance Recorder is permanently
creating new records.
The Disturbance Recorder shows a high
number of created disturbance records. This
number is growing steadily over time
(<Operation/ Recorders / Disturb rec>).
To observe this phenomenon in Smart view,
please execute a „refresh“ (F5 or Ctrl+F5).
Check the following issues:
1. Check which events are configured to trigger the
Disturbance Recorder (<Device Para/ Recorders / Disturb
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
Disturbance Recorder. But this is less advisable.
