Figure 304: 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.

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/Disturbance
records menu. Deleting all disturbance recordings at once also clears the pre-trigger
recording in progress.
Storage mode
The disturbance recorder can capture data in two modes: waveform and trend mode.
The user can set the storage mode individually for each trigger source with the Storage
