System selection
System 3-P.n unbalanced load 3-phase (4-wire)
System 3-P unbalanced load 3-phase (3-wire)
System 3-P.1 (only AV5 and AV6)
balanced load 3-phase (3-wire) one
current and 3-phase to phase
voltage measurements
3-phase (4-wire) one
current and 1-phase (L1) to
neutral voltage measurement
System 2-P 2-phase (3-wire)
System 1-P 1-phase (2-wire)
Transformer ratio
VT (PT) 1.0 to 999.9 / 1000 to 6000
(only AV5 and AV6)
CT 1.0 to 999.9 / 1000 to 9999
/ 10.00k to 60.00k (only
AV5 and AV6). The maxi-
mum VT by CT ratio is
3150 for AV5_PF models,
4629 for AV5_X models,
14529 for AV6_X models.
Note 1: for MID complaint
applications the maximum
power being measured is
25 MW for AV5_PF models,
51 kW for AV9_PF and
AV2_PF models. Note 2:
for non-MID complaint
applications the maximum
power (calculated as maxi-
mum input voltage and
current) being measured
cannot exceed 66 MW for
AV5_X models, 62 MW for
AV6_X models, 51 kW for
AV2_X models and 54 kW
for AV9_X models.
Filter
Operating range 0 to 100% of the input dis-
play scale
Filtering coefficient 1 to 32
Filter action Measurements, serial output
(fundamental variables: V, A, W
and their derived ones).
Displaying Up to 3 variables per page
(see « Display pages »)
8 different set of variables
available (see « Display
pages ») according to the
application being selected
Reset By means of the front
joystick:
- dmd and dmd max;
- total energies (kWh and
kvarh) and gas/water;
- partial energies and
tariffs: kWh, kvarh
Easy connection function
AV2 and AV9 models Automatic phase sequence
detection with current and
voltage synchronisation.
AV5-AV6-AV2-AV9 models For all the display
selections, both energy
and power measurements
are independent from the
current direction. The
displayed energy is always
“imported” with the only
exception of “F” and “H”
types (see “display pages”
table). For those latter
selections the energies can
be either “imported” or
“exported” depending on
the current direction.
