SA300 Substation Automation Unit 139
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.
An example of the IEEE 1159 statistics report is shown in the following picture.
