Power quality standards compliance reporting

Your meter can measure and record compliance data for the following power quality standards.
EN 50160
The EN 50160 framework includes ION modules such as Flicker, Mains Signaling Evaluation,
Harmonics Evaluation, and Voltage Harmonics.
DATA LOSS
Failure to follow these instructions can result in data loss.
Use an Uninterruptible Power Supply (UPS) to help maintain EN 50160 framework operation
during a power outage.
For more information about EN 50160, see the Power Quality: ION Meters and EN50160:2010
technical note, available on www.usa.siemens.com/pds.
IEEE 519
The IEEE 519 framework includes ION modules, such as: Harmonics Evaluation, Harmonics
Measurement, and Counter.

Disturbance direction detection

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. In the diagram below, meters (B), (C) and (D)
are installed on the power consumer side, while meter (E) is installed on the utility side.
