Spikes
The Spikes counter is to be understood as the increase of the RMS value of the line-to-line
voltage above the set
V Spike Threshold
for a duration of less than 40 ms (increase in voltage of
short duration).
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 rapid voltage increases of equal duration may be evaluated differently
depending on their amplitude:

Counters (Spikes)
Description
Last time stamp
Date and time referred to the last
Spikes
counter record
Last value
Value of the last increase above the
Spikes
threshold [V]
Last duration
Duration of the last increase above the
Spikes
threshold [ms]
Actual number of S.
Count of
Spikes
referring to the current day
Actual [day -2 ... day -7]
number of S.
Count of
Spikes
detected in the last seven days of activity, calculated
using the unit's internal clock
Sags
In the
Counters - Day -1
and Counters - Cumulative submenus some counters for sags are
available:
Counters
Description
Sag.Short
Counts the times that any line-to-line voltage drops below the
V sag Th Short
threshold for longer than
V sag dur Short
Sag.Middle
Counts the times that any line-to-line voltage drops below the
V sag Th Middle
threshold for longer than
V sag dur Middle
Sag.Long
Counts the times in which any line-to-line voltage drops below the threshold
V sag
Th Long
for longer than
V sag dur Long
The count refers to the interval of the menu of reference (previous day or cumulative)
NOTE: since it is possible for an event to fall within more than one type, only the counter
related to the highest applicable type is increased (Long > Middle > Short)
