Above V Th and
Below V Th
In the
Counters - Day -1
and
Counters - Cumulative
submenus some counters are available for
sequence measurements:
Counters
Description
Over V Th
Counts the times when the average value of the positive sequence (with the sense of
rotation of the phases set: 1-2-3) or negative sequence (with the rotation direction of
the phases set: 3-2-1) exceeds
V Threshold High
. The count refers to the interval of
the menu of reference (previous day or cumulative)
Under V Th
Counts the times when the average value of the positive sequence (with the sense of
rotation of the phases set: 1-2-3) or negative sequence (with the rotation direction of
the phases set: 3-2-1) falls below
V Threshold Low
.
The count refers to the interval of
the menu of reference (previous day or cumulative)

V Interruption
(Interruption)
T
he counter
V Interruption
is to be understood as the reduction of the RMS value of the line-to-
line voltage below the
V Interruption
threshold.
Th
set, for a duration of less than 40 ms (short
voltage sag).
The counter is available in the two sub-menus
Counters - Day -1
and
Counters - Cumulative
(previous day or cumulative)
NOTE: Since the counter is based on the calculation of the RMS value, it is possible
that two interruption of equal duration may be evaluated differently depending on the
moment in which they occur:
