Transformer ratio
VT (PT) 1.0 to 999.9 / 1000 to 6000
(only A
V5 and AV6)
CT 1.0 to 999.9 / 1000 to 9999
/ 10.00k to 60.00k (only
AV5 and AV6). The maxi-
mum power being mea-
sured cannot exceed 210
MW (calculated as maxi-
mum input voltage and
current, see the “Accuracy”
paragraph before). The
maximum VT by CT ratio is
48600. For MID complaint
applications the maximum
power being measured is
25MW.

ilter action Measurements, serial output
(
fundamental variables: V, A, W
a
nd 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 curr
ent direction.
