6 Record Format and Naming, and Mass Storage Capacity
6.1 Record Format
Records comply with the COMTRADE standard IEEE C37.111-1999, IEEE Standard
Common Format for Transient Data Exchange for Power Systems . The ".dat", ".hdr",
".cfg", ".inf" and ".tri" files are zipped together in a ".zic" ( zi pped c omtrade) file for
faster transmission.
The ".zic" files are created following the RFC 1951, DEFLATE Compressed Data Format
Specification.
The ".hdr" files have the information about the Reason for the trigger and the location
of the fault, the md5sum of the ".dat" and ".cfg" files, and the status of the equipment
when the record was created.
The ".inf" files have the groups and the power lines parameters. The data are
formatted according to the requirements of Alstom's
Analise software.
The ".tri" files have the sequence of digital events. The data was formatted according
to the requirements of Alstom's
Analise software.
The following information about the register and the RPV311 can be found within the
.zic file:

Trigger cause

Date

Equipment health and sync status

Memory usage

Last power up

Firmware version

Identifier

Location

Owner
6.2 Record Naming
Records are named using the COMNAME methodology, according to IEEE C37.232,
Recommended Practice for Naming Time Sequence Data Files .
Fault, Disturbance, Steady-state, and Sequence of Events records are named as
follows:
STARTDATE,STARTTIME,TIMECODE,STATIONID,DEVICEID,COMPANY,DURATION,TYPE.
ZIC
Traveling wave records are named as follows:
STARTDATE,STARTTIME,TIMECODE,STATIONID,DEVICEID,COMPANY,DURATION,
