COMTRADE implementation overview
COMTRADE records are generated for sag/swell events. Configure your meter nominal voltages to enable waveform recording. COMTRADE records are stored as read-only files on your meter’s internal SFTP site, and are deleted when you perform a Master reset of the meter, upgrade firmware or make changes to the waveform recorders.
The meter is configured so COMTRADE records are generated for the default waveform recorders.NOTE: If you add additional waveform recorders and you want COMTRADE files generated for these new recorders, you need to configure a new COMTRADE module using ION Setup Advanced mode. You can configure up to three COMTRADE modules.
- The oldest COMTRADE record is overwritten by the newest record when the COMTRADE depth is exceeded.
See the COMTRADE and ION technology technical note, available from www.schneider-electric.com, for detailed information about COMTRADE file formats and implementation.
