Appendix H EN 50160 Conformance Tracking
Voltage Swells
The power monitor records voltage swells when the line-to-neutral voltage (for
Wye and split-phase metering modes) or line-to-line voltage (for Delta systems)
exceeds 110% of its nominal value. The duration and swell voltage (the maximum
value during the event) are used to classify voltage swells by using the categories
shown in Table 231
.
Transient Overvoltages
Conformance criteria for transient overvoltages are not specified in the standard.
Results
This section explains the results of EN 50160 conformance tracking.
EN 50160 Compliance Record
The PowerQuality.EN50160_Compliance_Results Data Table contains a
summary of conformance with EN 50160 compliance criteria. This table
aggregates the data that is logged in completed records in the EN 50160 weekly
and yearly logs. No in-process weekly or yearly log records are aggregated into the
compliance record. The content of the compliance record is shown in Table 232
.
