8.2.1.4 Sampling frequenciesThe sampling frequency of the disturbance recorder analog channels depends onthe set rated frequency. One fundamental cycle always contains the amount ofsamples set with the Storage rate parameter. Since the states of the binary channelsare sampled once per task execution of the disturbance recorder, the samplingfrequency of binary channels is 400 Hz at the rated frequency of 50 Hz and 480 Hzat the rated frequency of 60 Hz.Table 574:Sampling frequencies of the disturbance recorder analog channelsStorage rate(samples perfundamentalcycle)RecordinglengthSamplingfrequency ofanalogchannels, whenthe ratedfrequency is 50HzSamplingfrequency ofbinarychannels, whenthe ratedfrequency is 50HzSamplingfrequency ofanalogchannels, whenthe ratedfrequency is 60HzSamplingfrequency ofbinarychannels, whenthe ratedfrequency is 60Hz32 1* Recordlength1600 Hz 400 Hz 1920 Hz 480 Hz16 2* Recordlength800 Hz 400 Hz 960 Hz 480 Hz8 4 * Recordlength400 Hz 400 Hz 480 Hz 480 Hz8.2.1.5 Uploading of recordingsThe IED stores COMTRADE files to the C:\COMTRADE\ folder. The files can beuploaded with the PCM tool or any appropriate computer software that can accessthe C:\COMTRADE\ folder.One complete disturbance recording consists of two COMTRADE file types: theconfiguration file and the data file. The file name is the same for both file types.The configuration file has .CFG and the data file .DAT as the file extension.Section 8 1YHT530004D05 DMeasurement functions652 615 seriesTechnical Manual
