COMTRADE
COMTRADE is configured as part of the default waveform framework. COMTRADE records are generated for waveform records triggered by power quality events or manually.
COMTRADE files can be accessed from the meter’s internal FTP / FTPS server or through Modbus TCP (not available on serial), and is composed of two files:
File name extension |
Description |
---|---|
.cfg |
Configuration of event data |
.dat |
Event data records per .cfg file
|
By default:
-
The meter is configured to generate COMTRADE records for any sag/swell event.
-
The oldest COMTRADE record is overwritten by the newest record when the COMTRADE limit of 10 files is exceeded.
See the COMTRADE and ION technology technical note, available from www.se.com , for detailed information about COMTRADE file formats.
