under the sag limit (U<) or increases over the swell limit (U>).
There are four registers for both sags and swells in the fault
log. Each register will have start time, type (which phases),
duration, minimum, average, maximum voltage values of each
sag and swell event. Furthermore, there are total number of
sags and swells counters as well as total timers for sags and
swells.
The voltage power quality functions are located under the
submenu “U”.
