COMTRADE implementation
COMTRADE is configured as part of the default waveform recording framework.
COMTRADE records are created for sag/swell events. Configure your meter's nominal voltages to enable waveform recording. COMTRADE records are stored as read-only files on the meter’s internal SFTP site. A master reset, firmware upgrade, or waveform recorder change will delete the records.
Note: Sag/Swell alarms must be enabled when using COMTRADE. For details on how to set up Sag/Swell alarming, see Configuring sag/swell alarms using ION Setup.
By default:
- The meter is configured so COMTRADE records are created for
the default waveform recorders.
Tip: If you create a waveform recorder, the recorder will not create COMTRADE files by default. Configure a new COMTRADE module if you want COMTRADE files created by new recorders. You can configure up to three COMTRADE modules using ION Setup in Advanced mode. For more information on how to switch ION Setup to Advanced mode, see Meter configuration.
- The oldest COMTRADE record is overwritten by the newest record when the COMTRADE depth is exceeded.
Note: COMTRADE files can only be downloaded using an Ethernet connection. They cannot be downloaded using serial, modem, or Ethernet gateway connections.
