Counters - introduction
The main counters of the function are available in the
Measurements
–
Network Analyzer
menu, distributed
among several sections (page 36).
The extended list of all the measurements is available via Ekip Connect or by connecting to the bus system
NOTE:
the Additional List item in the following paragraphs contains the additional counters
that are only present via Ekip Connect; the type of reference counter is given in the
heading of the additional tables
V Sequences and V 3s
Sequences
Submenus
V Sequences
and
V 3s Sequences
have the following counters:
Menu
Parameter
Description
V Sequences
V seq pos
Positive sequence of period in progress [V]
V seq neg
Negative sequence of period in progress [V]
Last V pos seq
Positive sequence of period preceding the one in progress [V]
Last V neg seq
Negative sequence of period preceding the one in progress [V]
V 3s Sequence
V seq pos
Positive sequence calculated during the last three seconds [V]
V seq neg
Negative sequence calculated during the last three seconds [V]
Unbalance
Voltage unbalance calculated during the last three seconds [%]
Additional List
Counters (Sequences)
Description
Last time stamp
Date and time of last recording of the sequences
Counters (Sequences)
Description
Last value
Voltage unbalance relating to the period in progress [%]
Actual unbalance value
Voltage unbalance relating to the period preceding the one in progress
[%]
Last time stamp
Date and time of last recording of the unbalances
Actual number of U.
Counts the number of times that the average value of the ratio between
the positive on negative sequence (with direction of rotation 3-2-1) and
negative on positive sequence (1-2-3) exceeds the
Unbalance V Th
threshold; the count refers to the actual day
Actual [day -1 ... day -7]
number of U.
Counters relating to the number of unbalances detected in the last
seven days of activity, calculated using the internal clock of the unit
Cumulative number of U.
Cumulative counter of all the unbalances detected by the unit (sum of
the other counters or to be increased also for the previous days?)
NOTE:
all measurements of unbalances (Not balanced and Unbalance value) saturate at
200%
THD Current and THD Voltages
The
THD Current and THD Voltages
submenus have the following counters:
Menu
Counters
Description
THD Current
L1, L2, L3, Ne
Instantaneous harmonic distortion value of each current phase
THD Voltages
U12, U23, U31 Instantaneous harmonic distortion value of each line-to-line voltage
