Instruction manual –AQ F210 Feeder Protection IED 211 (292
)
4.4.3 Disturbance recorder (DR)
The disturbance recorder in AQ-2xx IED is a 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 9 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 file is based on standard IEEE Std
C37.111-1999. Captured recordings can be injected as playback with secondary testing
tools those support comtrade file format. Playback of files might help to analyze the fault or
can be simply used in educational purposes.
