Harmonics, voltage fluctuations, transient over-voltage conditions and other power
anomalies can wreak havoc on your equipment and processes. It is essential to fully
understand the quality of the power that is being delivered throughout the facility.
Detailed event information makes it possible to pinpoint the root causes of
problems—or prevent them from occurring.
In the past, basic power monitors were used to identify existing conditions on an electrical distribution system or to evaluate past problems. If you wanted to detect fast
voltage transients, you had to bring in portable power quality monitors that cost up to
$20,000 and usually required an outside consultant.
Eaton Power Xpert™ 4000/6000/8000 next-generation meters redefine the art of power
monitoring. Thanks to the latest technologies, we can now match the sampling rate of
those high-end systems in compact, affordable devices. These permanently installed
instruments monitor, record and analyze critical aspects of an electrical distribution
system—so you can optimize energy utilization, process performance and cost. Three
models are available:
• The Power Xpert 4000 meter provides core functions for monitoring power
consumption and power quality. This unit uses Delta Sigma technology to
sample circuits at 1024 samples per cycle for extremely accurate measurement
of harmonics and other events.
• The Power Xpert 6000 meter adds another level of sampling ability, using a
combination of voltage and duration to isolate sub-cycle oscillatory transients.
An optional 512MB memory card provides generous storage for waveforms and
other event data.
• The Power Xpert 8000 meter adds the ability to capture very fast transients by
sampling at 6 MHz — 100,000 samples per cycle. That’s a sample every 166
nanoseconds—six samples every millionth of a second, across three input
channels and neutral-to-ground.
The Graphic Display Module takes away the guesswork of
how to navigate the meter, it’s as simple as “twist-and-select”
In designing these power quality instruments, Eaton set out to demystify power
quality— to take highly specialized data and convert it into useful information that
doesn’t require a power guru or consultant to understand. The result is an
uncommonly easy-to-use interface and new graphical representations of complex
power quality data—delivered via email, over the Web and to third-party applications.
With these capabilities, your power team can predict and prevent power quality
problems before they lead to equipment malfunction, overheated circuits and system
failure.
Power Xpert 4000/6000/8000 Product Highlights
Very fast transient sampling
Impulsive transients can peak
and decay in mere microseconds. Some power quality
meters that tout “fast transient
detection” will sample voltage
at 5 MHz per channel or 83,333
samples per cycle—adequate
to characterize most impulsive
transients. In contrast, the
Eaton Power Xpert 8000 meter
samples high-speed transients
at 6 MHz— 100,000 samples
per cycle.
High-speed sampling of harmonics and other events
Eaton Power Xpert
4000/6000/8000 meters sample
routine voltage at 1024 samples
per cycle, using a Delta Sigma
converter that accurately measures all power system frequencies. These data points are then
cleansed to eliminate anti-aliasing error, a mathematical quirk of
power measurement that would
otherwise skew results.
The Power Xpert meter then
records a statistically representative 256 samples per cycle from
this cleansed data. Because
the data has been run through
anti-aliasing filters, the resulting
256 samples are actually more
accurate than a higher number
of samples that have not been
through this cleansing process.
Statistically derived trending
In the past, power meters
graphed a reading of power
parameters at designated time
intervals. How high does voltage go?
Power Xpert 4000/6000/8000
meters go beyond a simple
snapshot view. In addition to
recording the value of power
parameters every x number of
minutes, these meters record
the average, minimum and
maximum of that parameter
over that interval. The result is
a much more accurate view—a
composite picture of activity
from the whole interval, not just
a moment in time.
Power Xpert 4000/6000/8000
meters also display a composite
health check known as a Power
Quality Index. The PQ index
combines several power quality parameters, running data
through statistical analysis, and
returning a color-coded, graphical display of overall power qual-
ity. Green-yellow-red indicators
provide an at-a-glance view of
how well power quality is measuring up to what is normal for
that circuit— now and historically.
Self-learning capability—What
is “normal?”
How do you determine what is
“normal” for a circuit? Older
power monitors required complicated set-up of thresholds and
triggers; it was difficult to set
these limits correctly. Power
Xpert meters simplify this process with self-learning capability. In learning mode, the meter
monitors activity on the circuit,
characterizes what is normal
for that circuit, and statistically
derives proper limits for routine
health-checks and alarms. No
operator intervention is required.
You can also over-ride the selflearned alarm thresholds and
apply your own settings, if
desired.
Sag and swell recording
The meter records 60 cycles of
waveform at 256 samples per
cycle, including 30 cycles of preand post-event data. This information is stored in the meter in
non-volatile, flash memory using
an industry-standard Comtrade
format. Waveforms can be
viewed via the embedded Web
server, automatically sent out
as Comtrade attachments to an
email after an event, or retrieved
from an ftp (file transfer protocol) directory in meter memory.
Representation of power
events on an ITIC curve
The ITIC (Information
Technology Industry Council)
curve describes how much
(or how little) voltage your IT
equipment can sustain without
damage, over what length of
time (nanoseconds to seconds).
When you can plot power
events in this broader context—
relative to multiple variables—
you can identify trouble that
may be brewing, not just after a
threshold has been exceeded.
Of the few meters that can
plot events on an ITIC curve,
most require special software
to do it. Eaton Power Xpert
4000/6000/8000 meters require
no special software. Right out of
the box, these meters populate
and display ITIC curves on both
the local display and the Web
interface.
Intuitive, visual interface
In the race to outdo each other with technical features, some power
meter designers have created the equivalent of yesterday’s VCR— a
promising tool that no one really feels comfortable programming and
using. Eaton saw an opportunity to redefine the paradigm. Who
says power quality has to be complex? Our mission was to bring
sophisticated capabilities to people who had a vested interest in
power quality but were not necessarily electrical engineers or consultant specialists.
The user interface makes it natural and intuitive to assess power
conditions in your facility—at a high level or in detail. Users have
two choices for viewing power quality information from the meter:
• Large graphical display unit. The crisp, 320x240-pixel, backlit
display is mounted near the meter or networked to support up to
16 meters. This local display provides intuitive graphics, such as
the at-a-glance Power Quality (PQ) index, ITIC curve and
meter summary.
Navigating and drilling down through the views is easy with
“twist and click” control. Simply turn the navigation control dial
until the arrow lands on the menu selection you want to display,
and press the button. It’s that easy.
• The Web. A Web server application is built right into the meter.
With a password-protected Web interface, you have many
options for assessing power conditions and utilization records.
Click to drill down into detail, zoom out to see the broader
context, modify reporting parameters and more.
Both the local graphic display and the embedded Web server present real time, historical, and event information in a browser style
graphical format. It’s easy to interpret key circuit information, such
as current loading, voltage and power levels, power factor, energy
usage, I/O status, power quality measurements, harmonic plots,
disturbance and transient waveforms and a summary of ITIC disturbances. The Web server adds yet more power quality information,
such as harmonic distortion, flicker, crest factor, k-factor and more.
The Quick Start Guide aids in getting the meter and the display modules
quickly and easily installed.
