Disturbance Recorder Settings - ABB Eagle Programming Manual

If inrush is detected, then the sectionalizer will not consider that particular count. Fresh
activation of FPI is required after the inrush detection to increment the count.
When the number of counts reaches equal to the set Count, the device opens the CB.
While incrementing counts, if further no counts are increased within set Reset time, the
counter is reset back to zero.
The activation and deactivation of FPI, activation and deactivation of sectionalizer mode,
Increment of counts & activation of Trip output are available in the events page.

4.4.8. Disturbance Recorder Settings

Disturbance Recorder (DR) can be triggered by 16 binary events. The events which can
trigger the DR can be configured from the Settings -> Disturbance Recorder page.
Pre and post recording time defines data recording time before DR trigger activation and
after DR trigger point respectively. Whereas fault recording time defines the max recording
time under fault condition. The recording of analog and digital value starts before the DR
trigger point for time period equal to Tpre and it continues for time Tpost after deactivation
of DR Trigger signal. Fault time is a varying quantity which is max equal to Trec setting and
can be shorter in case were DR trigger signal deactivate before Trec time.
The device stores a maximum of 250 DRs. If settings Overwrite Enable is activated, then
post the 250 DRs, the oldest DR is overwritten with the latest. If the setting is disabled,
then post 250 DRs no new DRs will be stored.
