Disturbance Direction Detection Events; Comtrade; Comtrade Implementation - Siemens 9810 Series User Manual

9410 series - User manual
The arrows show the direction the meters have determined for the disturbance. With this
information, you can determine that the disturbance occurred between meter (B) and meter (C)
and can focus on that section of your system to find the cause of the disturbance.

Disturbance direction detection events

The results of the disturbance direction detection algorithm appear in the meter's event log.
The image below shows an example of how the Disturbance Direction Detection event appears in
your meter's event log when viewed using ION Setup.
NOTE: You can view your meter's event log through ION Setup, the meter webpages or display.
See ION Reference, available from www.usa.siemens.com/pds, for more information about the
Disturbance Direction Detection module.

COMTRADE

Your meter can generate COMTRADE files and store them on the meter's internal SFTP site.
COMTRADE stands for COMmon format for TRAnsient Data Exchange defined by IEC 60255-24,
and defines a common format for power quality event (disturbance) data in order to simplify
retrieval, analysis and exchange of disturbance data between multiple sources and vendors.
The format of your meter's COMTRADE files is as defined by IEC 60255-24.
COMTRADE can be used in conjunction with IEC 61850.
See the COMTRADE and ION technology technical note, available from
www.usa.siemens.com/pds, for details.

COMTRADE implementation

COMTRADE is configured as part of the default waveform recording framework.
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.
By default:
• 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.
