Disturbance direction detection overview
Your meter has disturbance direction detection capabilities to help you determine the
location of a power system disturbance.
When a disturbance occurs, the meter analyzes the disturbance information to
determine the direction of the disturbance relative to the meter. This analysis includes
a confidence level indicating the level of certainty that the disturbance is in the
determined direction, and is stored in your meter’s event log.
Disturbance direction detection is enabled on your meter by default and does not
require any additional configuration beyond setting the nominal voltage and nominal
frequency.
Disturbance direction detection can help locate the source of a disturbance when used
in a system of disturbance direction detection devices, as shown in the diagram below.

The arrows show the direction the meters have determined for the disturbance. With
this information, you can determine that the disturbance occurred between meter #1
and meter #2, and can focus on that section of your system to find the cause of the
disturbance.
Disturbance direction detection events information
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 the display and ION Setup.
