Counters -
preface
The main function counters are available in the
Measurements - Network Analyzer
menu (page
29), distributed across several sections.
The extended list of all measurements is available via Ekip Connect or with system bus
connection.
NOTE: in the following paragraphs, the
Supplemental List
item shows the additional
counters present only via Ekip Connect. The counter type of reference is shown in the
header of the supplementary tables
Sequence V and
Sequence V 3s
The
Sequence V
and
Sequence V 3s
submenus have the following counters:
Menu
Counters
Description
V sequence
V seq pos
Positive sequence relative to the current period [V]
V seq neg
Negative sequence relative to the current period [V]
Last V pos
Positive sequence relative to the previous period [V]
Last V neg
Negative sequence relative to the previous period [V]
V 3s
sequence
V seq pos
Positive sequence calculated in the last three seconds [V]
V seq neg
Negative sequence calculated in the last three seconds [V]
Unbalanced
Voltage imbalance calculated in the last three seconds [%]
Supplemental list
Counters (Sequences)
Description
Last time stamp
Date and time referred to the last record of the sequences
Counters (Unbalance)
Description
Last value
Voltage imbalance related to the current period [%]
Actual unbalance value
Voltage imbalance related to the previous period [%]
Last time stamp
Date and time referred to the last record of imbalances
Actual number of U.
Counts the times when the mean value of the ratio of positive to negative
sequences (with the sense of rotation 3-2-1) and negative to positive
sequences (1-2-3) exceeds the threshold
Unbalance V Th
. The count refers
to the current day.
Actual [day -1 ... day -7]
number of U.
Counters referred to the number of imbalances detected in the last seven
days of activity, calculated using the unit's internal clock
Cumulative number of
U.
Cumulative counter of all imbalances detected by the unit (sum of the other
counters or also added to the previous days?)
NOTE: all imbalance measurements (not balanced and Unbalance value) saturate
when it reaches 200%
THD Current and
THD Voltages
The
THD Current
and
THD Voltages
sub-menus have the following counters:
Menu
Counters
Description
THD Current
L1, L2, L3, Ne
Real-time value of the harmonic distortion of each current phase
THD Voltage
U12, U23, U31
Real-time value of the harmonic distortion of each line-to-line
voltage
