Figure 478: Disturbance recorder file naming
The naming convention of 8+3 characters is used in COMTRADE file naming. The file
name is composed of the last two octets of the protection relay's IP number and a running
counter, which has a range of 1...9999. A hexadecimal representation is used for the IP
number octets. The appropriate file extension is added to the end of the file name.
8.2.2.6 Deletion of recordings
There are several ways to delete disturbance recordings. The recordings can be deleted
individually or all at once.
Individual disturbance recordings can be deleted with PCM600 or any appropriate
computer software, which can access the protection relay's C:\COMTRADE folder. The
disturbance recording is not removed from the protection relay's memory until both of the
corresponding COMTRADE files, .CFG and .DAT, are deleted. The user may have to
delete both of the files types separately, depending on the software used.
Deleting all disturbance recordings at once is done either with PCM600 or any appropriate
computer software, or from the LHMI via the Clear/Digital fault recorder menu.
Deleting all disturbance recordings at once also clears the pre-trigger recording in
progress.
