Power Xpert Meter 4000/6000/
8000 Embedded Web Server
The Power Xpert Meter 4000/
6000/8000 embedded Web
server offers Eaton
customers a new level of
accessibility to the critical
information required to
manage their electrical
distribution system. The Web
server includes real-time
circuit information in both
numeric and graphical visual
formats to help monitor
circuit parameters such as
current loading, voltage and
power levels, power factor,
THD, Flicker and more. The
Web server also provides
energy and demand readings
with graphic usage plots to
help analyze energy usage
patterns. Energy readings
include kWh, kVARh,
delivered and received and
kVAh with time of use and
RTP displays. The interval
energy usage plot includes
the ability to do week-to-
week and month-to-month
energy consumption
graphical comparisons for
benchmarking purposes. The
embedded Web server will
also display in simplified
Chinese if connected to a
computer configured for
Chinese language.
Both the Power Xpert Meter
4000/6000/8000 embedded
Web server and the local
graphic display support
graphical trend charts of key
circuit measurements such
as current, voltage, power
and energy. The trend chart
supports a zoom feature that
allows the user to view data
over a short period of 16
hours up to 4 years. The trend
chart includes zoom in/out
buttons and a horizontal slider
bar control to manage
scrolling forward and backward
through the data. Trend charts
of basic readings include
minimum, maximum and
average readings. Trend
charts of interval by interval
energy data also display
peak demand.
Note: For remote access and
networking capabilities such as
connecting to a LAN/WAN, use
the optional Communications
Expansion Card (CEC).
Sag/Swell/Transient Capture
and Recording
60 cycles of waveform are
oversampled at 4096 samples
per cycle (Power Xpert Meter
4000/6000), filtered through
anti-aliasing and recorded at
512 samples per cycle and
post event data. The Power
Xpert Meter 8000 samples at
a rate of 100,000 samples per
cycle. Embedded Web server
supports viewing of triggered
waveforms one channel at a
time and includes the ability to
zoom and to scroll horizontally
using a slider bar.
The Power Xpert Meter
6000/8000 Series have
preconfigured (600 volts and
below) trigger settings for
sags, swells and transients,
and do not require additional
setup by the user. Waveforms
are stored in non-volatile flash
memory using an industry
standard COMTRADE
format. Waveforms can be
automatically sent out as
COMTRADE attachments to
an e-mail following an event,
or can be retrieved from an
FTP (File Transfer Protocol)
directory structure in
the Power Xpert meter
module’s memory.
Historical Trend Logging
The Power Xpert Meter 4000/
6000/8000 records historical
data for graphical viewing
from the Local display or
the embedded Web server.
Graphical views of historical
data support pan and zoom.
145 standard metering
parameters are logged as
part of the standard meter
functionality including min./
max. and average for each
parameter. The averages are
calculated over the interval
period. The minimum and
maximum readings are based
on 200 ms calculations.
Storage capacity for standard
trend plots includes all of the
following intervals:
●
Every 5 minutes for
48 hours (2 days)
●
Every 15 minutes for
192 hours (4 days)
●
Every hour for 28 days
(4 weeks)
●
Every 8 hours for
56 weeks
●
Every week for 44 months
Note: Trend plot data can be
easily exported to third-party
applications, such as Microsoft
Excel in csv-file format.
In addition, metered
parameters are automatically
stored on the built-in FTP
Servers, where they can be
easily copied and imported
into third-party applications
for benchmarking and
analysis. Logs on the FTP
Server include the min./max.
and average for 145 standard
metering parameters at
5-minute intervals.
Storage capacity for
trend data:
●
6 days of 5-minute
interval trend data
●
Capacity=18,144 intervals
Energy Profile Data
The Power Xpert Meter 4000/
6000/8000 records Real and
Reactive energy forward,
reverse, net and absolute
sum, as well as Apparent
energy (kVAH). Up to 8 status
inputs can be configured as
energy accumulators for
counting KYZ pulse inputs
(option). These readings are
stored over a configurable
interval from 1 to 60 minutes,
as well as in daily and
weekly totals.
With the optional LAN/WAN
Ethernet Communication
Expansion Card (CEC), users
can easily configure the
meters to send periodic
e-mails at user-defined
intervals of energy
consumption and power
demand. E-mails contain
a summary of readings per
rate structures and also have
the actual measurements
attached to the E-mail’s
body as a CSV file in a
ZIP container.
In addition, metered
parameters are automatically
stored on the built-in FTP
Server, where they can be
easily copied and imported
into third-party applications
for benchmarking and
analysis. Logs on the FTP
Server include energy
consumption logs, one
for every month in CSV
file format, trended
measurement logs also
in CSV file format and
waveform captures in
COMTRADE file format.
Storage capacity for energy
profile data:
●
62 days of 15 minute
interval energy and pulse
interval data.
●
Fixed interval capacity
= 5952 intervals.
Configurable intervals
from 1 to 60 min
●
372 days of 1 day
accumulated energy and
pulse interval data
●
208 weeks of 1 week
accumulated energy
and pulse interval data
Energy and Demand
Comparisons
Energy and demand usage
patterns can be analyzed with
the month-to-month, week-
to-week comparison chart
built into the meter. Raw
data can be exported with
the “Save Table” option to
other applications, such as
Excel, for further analysis
and graphing.
