5.5.6 Disturbance recorder (DR)
The disturbance recorder is a high-capacity (64 MB) and fully digital recorder integrated to the
protection relay. The maximum sample rate of the recorder's analog channels is 64 samples per cycle.
The recorder also supports 95 digital channels simultaneously with the twenty (20) measured analog
channels.
The recorder provides a great tool to analyze the performance of the power system during network
disturbance situations. The recorder's output is in general COMTRADE format and it is compatible with
most viewers and injection devices. The files are based on the IEEE standard C37.111-1999. Captured
recordings can be injected as playback with secondary testing tools that support the COMTRADE file
format. Playback of files might help to analyze the fault, or can be simply used for educational
purposes.
Analog and digital recording channels
Up to 20 analog recording channels and 95 digital channels are supported. The available analog
channels vary according to the device type.
