Description
The
EMS
(Electrical
Measurement
Supervisor)
has
advanced
analysis
functions
that
allow
the
measurement
of
the
main
electrical
parameters:
voltage,
current,
frequency,
power
factor,
active
and
reactive
power,
active
and
reactive
energy.
The
instrument
allows
the
measurement
and
analysis
in
real
time
of
electrical
parameters,
also
verifying
the
quality
of
the
energy
thanks
to
THD
measurement.
Bidirectional
metering
of
energy
allows
both
production
and
consumption
of
energy
to
be
monitored
with
a
single
device.
All
information
monitored
by
the
analyzer
can
be
transmitted
to
remote
locations
through
communication
interfaces
RS485,
Ethernet
with
the
support
of
numerous
protocols
including
Modbus
RTU,
Modbus
TCP/IP
and
Profibus
DP.
Interaction
with
the
control
and
supervision
systems
is
possible
using
inputs
and
outputs,
all
programmable.
EMS
reads
and
displays
the
energy
values
measured
in
other
energy
meters
connected
to
the
network.
This
is
achieved
thanks
to
digital
inputs,
which
are
able
to
acquire
the
impulses
generated
by
the
counters.
In
this
case,
EMS
acts
as
a
data
concentrator.
It
not
only
collects
information
from
the
electricity
meters
but
also
from
the
water,
gas
meters
or
other.
EMS
allows
a
complete,
in-depth
analysis
of
the
network
quality
thanks
to
the
measurement
of
the
harmonic
distortion
(20
th
order)
of
the
voltage
and
current
signals.

4 Timebands, optionally is possible to choose 8 or 16 Timebands
To enable one or more options it’s necessary to input a code (Enable option item) in the instrument setup. If the options are
requested at the moment of the order the code is already loaded and showed on the instrument report. After the installation, to
enable one or more options it is necessary to request the code to the seller, sending the serial number. The seller will deliver the
new code to load in the instrument setup.
