Power Xpert Meters

The new Power Xpert® line of Electronic Meters has three main series and each provide unique additional functions.

• 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.

1 millisecond time resolution - most accurate time available

Harmonics, voltage fluctuations, transient overvoltage 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. With up to one millisecond time stamping accuracy available via GPS and IRIG-time sources, Power Xpert Meters register the sequence of events in a time-synchronized environment. Based on National Institute of Standards and Technology (NIST) atomic time, you can count on the most accurate time available. 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.

Built-in graphing - six samples every millionth of a second

Power Xpert 4000/6000/8000 next-generation meters redefine the art of measuring and monitoring power quality. Thanks to the latest technologies, these metering instruments are able to measure, trend, analyze and capture waveforms while serving web pages to users over the Internet, along with simultaneous FTP downloading and comma separated values (CSV) exporting capabilities. No matter if you are a PhD level power quality engineer or an IT system administrator, these instruments will provide you with the level of information you need, in an easy to understand graphical user interface at astonishing speeds of six samples every millionth of a second, if necessary.

Easy to use interface - demystifies power quality

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 analysis 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.

1 gigabyte of storage capability - store and trend 5-10 years worth of data

Having enough storage capacity is a critical factor at this level of power quality instrumentation. How long can I store data locally on the power quality meter before the system will have to start overwriting previously captured information? A Power Xpert Meter has 512 MB of storage as standard and can be upgraded all the way to 1 GB. In a typical power quality environment this would provide storage capability for 5-10 years depending on the meter model.

Built-in ITIC performance curve analysis - Takes the guesswork out of understanding the severity of IT power quality events

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 could cause damage or may be brewing. Of the few meters that can plot events on an ITIC curve, most require special software to do it. Eaton's 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.

ITIC curves

The Power Xpert 6000 and 8000 meter models automatically plot events on the ITIC curve. The user can drill down on any specific event and get information on where exactly the event hit and what was its magnitude and duration. With the optional Power Xpert Network Time Server, all events get time stamped at a 1 millisecond synchronized resolution. The ITIC Web page includes counters to track the occurrence of disturbances and a pass/fail summary. In addition, selecting any disturbance counter links to a detailed event view of the disturbances in that ITIC category. Disturbance waveforms can be viewed from the browser.
