Sampling frequencies

The sampling frequency of the disturbance recorder analog channels depends on the set

rated frequency. One fundamental cycle always contains the amount of samples set with

the Storage rate parameter. Since the states of the binary channels are sampled once per

task execution of the disturbance recorder, the sampling frequency of binary channels is

400 Hz at the rated frequency of 50 Hz and 480 Hz at the rated frequency of 60 Hz.

Uploading of recordings

The protection relay stores COMTRADE files to the C:\COMTRADE\ folder. The files

can be uploaded with the PCM600 or any appropriate computer software that can access

the C:\COMTRADE\ folder.

One complete disturbance recording consists of two COMTRADE file types: the

configuration 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.
