It is also possible to choose the way of sorting the events. By default they are sorted by
time, but they can also be sorted by the type of event.
At the top of the Data Table you can find info about the file: the File name and the
mode in which the VoltScanner has recorded this file (Event & Transient or Periodics).
By clicking on the Settings Info button, you can see with which thresholds, VoltScanner
was recording data in the current file.
By clicking the
EN 50160
button, the software performs frequency analysis according to
the EN 50160 standard which requires:
•
99.5% of the mean values measured over 10 seconds must be within the range
±1% of the nominal frequency.
This analysis also counts the interruptions and swells plus dips on the L-N line. The
results of this EN 50160 analysis are in a special table at the top of the Data Table:
•
Events - number of swells and dips on the L-N line. The limit is by default 100.
•
Interruptions - number of interruptions. The limit is by default 100.
•
Frequency - percentage of the mean values measured over 10 seconds that are
within ± 1% of the nominal frequency. The limit is 99.5%.
If all of these results are within their limits, overall EN 50160 evaluation is OK, otherwise
NOT OK.
