5.6.3. Disturbance recorder (DR)
The disturbance recorder is high capacity (60 Mbyte) and fully digital recorder integrated to protection
relay. Maximum sample rate of the recorder analog channels is 64 samples per cycle. The recorder
supports 32 digital channels simultaneously with measured 20 analog channels.
The recorder provides great tool to analyze the performance of the power system in network
disturbance situations. Recorder output is in general comtrade format and it is compatible with most
viewers and injection devices. Comtrade le is based on standard IEEE Std C37.111-1999. Captured
recordings can be injected as playback with secondary testing tools those support comtrade le
format. Playback of les might help to analyze the fault or can be simply used in educational purposes.
Analog and digital recording channels
Up to 9 analog recording channels and 32 digital channels are supported simultaneously. Possible
analog channels vary according the IED type. All analog channels are presented below:
Table. 5.6.3. - 226. Analogue recording channels can be chosen between channels represented in table below. Availability of
signals depend on the hardware if the IED.
