6.1.3 Recorded data
The protection relay is provided with intelligent and flexible functionality that
collects different kinds of data. The recorded data gives substantial information for
post fault analysis.
• Disturbance records
• Events
6.1.3.1 Creating disturbance recordings
Normally disturbance recordings are triggered by the protection relay applications
but the recording can also be triggered manually.
1. Select Main menu/Disturbance records.
2.
Select Trig recording with
