The IEEE 1159 statistics is reported within the selected time
range on either a weekly, or yearly basis.
Statistics of power quality incidents for voltage imbalance,
harmonics, flicker and frequency variations are given on a per
week basis. The report shows the number of incidents, and a
total time and a percentage of the observation time within
which the characteristic exceeds the standard limit.
For voltage transients, sags, swells and interruptions, the
report gives the yearly statistical data classified by voltage
magnitude and duration.
