Power Xpert 2000 Embedded
Web Server
The Power Xpert Meter 2000
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
information in both numeric
and graphical visual formats
to help monitor parameters
such as current loading,
voltage and power levels,
power factor, THD 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.
The Power Xpert Meter 2000
embedded Web server
supports graphical trend charts
of key measurements such as
current, voltage, power and
energy. The trend chart
supports a zoom feature that
allows the user to view data
over predefined ranges from
as little as 16 hours to as much
as 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.
Waveform Display
The Power Xpert Meter 2000
can record waveforms at up to
512 samples per cycle.
Waveform captures are
automatically stored on the
FTP server in the IEEE
standard COMTRADE file
format. This allows users to
view and analyze the
waveforms in any standard
free-of-charge or commercial
COMTRADE file viewer.
Historical Trend Logging
The Power Xpert Meter 2000
records historical data for
graphical viewing from the
embedded Web server.
Graphical views of historical
data support pan and zoom.
Over 100 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.
Energy Profile Data
The Power Xpert Meter 2000
records Real and Reactive
energy forward, reverse, net
and absolute sum, as well
as apparent energy (kVAH).
These readings are stored
on a fixed 5 minute interval.
Up to 4 status inputs can
be configured as energy
accumulators for counting
KYZ pulse inputs.
Demand Comparisons
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 as a.csv file with the
“Save Table” option to other
applications for further
analysis and graphing.
Event Triggers
The Power Xpert Meter 2000
has two levels of configurable
event triggers:
●
On-board meter limits
(PXM 2260/2270/2280/
2290)
●
On-board gateway
card limits
The on-board meter limits
can be set for any measured
parameter, for up to 16 limits.
If either of the 16 limits are
exceeded, an alarm condition
will be present and illuminate
one of the LEDs on the meter
faceplate. The on-board
meter out of limits can also
be used to energize a relay
output, if so equipped.
The on-board gateway limits
can trigger an alarm off of any
measured parameter on any
of the PXM 2000 model
series. These triggers permit
pickup, reset and pickup
delay to be configured by
the user.
Event Logging
The Power Xpert Meter
2000 embedded Web server
allows the user to view a
list of triggered events. In
addition, a separate system
log records system operations
such as resets.
E-mail
The Power Xpert Meter 2000
contains the ability to send
e-mails based on an event
that has been triggered or
cleared along with the option
to send an event or data log
file. The Power Xpert Meter
2000 also has the ability to
send a configurable periodic
e-mail with meter
information.
Inputs and Outputs
Power Xpert Meter 2000 is
available with a standard KYZ
output and optional digital I/O
cards that includes:
●
Two relay outputs/two
status inputs
●
Four KYZ pulses/four
status inputs
●
Four analog outputs
0–1 mA
●
Four analog outputs
4–20 mA
Inputs can also be configured
for demand synch and pulse
counting. Inputs selected for
pulse counting can be scaled.
Accumulated pulse recordings
are maintained in profile
memory. Outputs can be
used for alarm annunciation.
