Uploading of recordings
The protection relay stores COMTRADE files to the C:\COMTRADE\ folder. The files
can be uploaded with the PCM tool or FTP 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.
