, there is only one magnitude limit but four
duration limits for interruption classification. Now the event and counter type depends
only on variation duration time.

Generally, no event detection is done if both the magnitude and duration requirements are
not fulfilled. For example, the dip event does not indicate if the TRMS voltage magnitude
remains between
Voltage dip set 3
and
Voltage dip set 2
for a period shorter than
VVa dip
time 3
before rising back above
Voltage dip set 3
