Real Time Readings & Waveform Display



Historical Trends for Any Perameter

Multipart Approach to Precision in Accuracy
The Nexus™ 1500 Meter is the first device of its kind to utilize EIG’s patent pending Accu-measure™ technology. Accu-measure™ technology is a technique based on a multipart approach that allows a field-mounted metering device to achieve laboratory accuracy.

8 Independent 16 Bit A/D Converters
Eight 16 Bit A/D converters provide supreme sampling accuracy and resolution - no sample skews causing accuracy errors.

Dual Internal References
The unit auto adjusts to dual internal references. These references ensure that the monitoring equipment maintains its calibration.

Auto-calibration with Temperature Compensation
The Nexus™ 1500 Meter uses an auto-calibration technique that recalibrates the unit on the fly when the temperature changes more than 5 degrees Centigrade, thereby monitoring for accuracy over temperature.

Precision Accuracy Specifications
With Accu-measure™ technology, this unit far exceeds all ANSI C-12 and IEC 687 accuracy specifications. The unit offers 0.08% watt-hour accuracy.

16 Bit Waveform and Fault Recorder
The unit records up to 1024 samples per cycle for an event with 10MHz voltage transient sampling. Voltage and current are recorded with pre- and post-event analysis. Fault recording offers 8x full scale capture capability. All voltage and current readings are recorded using a 16 bit A/D converter providing precise waveform resolution. Both hardware and software triggers are available to activate a waveform recording, which can be used for power quality surveys, fault analysis, breaker timing, etc.

Subcycle Transient Recorder
The Nexus™ 1500 Meter is equipped with 4 independent 10MHz analog to digital converters that measure transient samples 10 million times per second.
The unit records subcycle transients on voltage and current readings. It monitors switching noise from capacitors, static transfer switches, SCRs and many other “power quality harmful” devices. Transients are often the cause of intermittent and expensive periods of downtime. Without the Nexus™ 1500 Meter, solving these problems is often impossible.

Phasor Analysis
The monitor provides a phase angle analysis between the voltage and current channels, allowing for efficiency and system-integrity analysis.

EN50160 Flicker and Compliance Monitoring
It is important to maintain a source of high quality power to insure efficient operations. One particular source of disturbance that can have very negative effects is Flicker. Flicker consists of low frequency (less than 24 Hz) to intermittent line disturbances on the power line. Aside from effects on equipment, disturbances of this type can have negative effects on people.

One particular example of this is the flickering of light sources that can affect humans in different ways, depending on the severity.

The Nexus™ 1500 Meter complies fully with the Flicker requirements of EN50160 and includes:

- Flicker Evaluation-Instantaneous readings suitable for online monitoring; Short Term Readings (PST - 10 Min)

- Logging and monitoring - Long Term Readings (PLT - 4 hour) - logging and monitoring

- Polling - Pinst, Pst, Pst Max, Pst Min, Plt, Plt Max, Plt Min values

- Log Viewer (View graphed values Pst and Plt for Va, Vb and Vc or displayed values including Max and Min.)

Providing Advanced Metering Data Integration with the Web
Total Web Solutions is an advanced Ethernet communication architecture allowing you to display metering data and host your meter power information web page directly on a Nexus™ meter. The Nexus™ meter directly hosts the web data without any need for dedicated server software, ActiveX Controls or Java Applets. The meter does the data collection, the formatting and the page hosting. Additionally, this solution is very Information Technology Department friendly because it creates almost no network traffic and provides all formatted data through an HTTP interface without resident client software.

Advanced Features Include:
• Direct Web Page Hosting With Live Readings
• Read Direct From Meters (No Server Software Needed)
• Low-Cost / High Functionality

WebExplorer
(Directly Host Metering Data)
EIG’s WebExplorer provides you with direct access to all power data through Internet Explorer without needing to download ActiveX Controls or Java Applets.

• Easily Incorporated Into Any Existing Web Applications

WebMod
(Open Architecture 3rd Party Integration)
The 10/100BaseT design allows the unit to speak with 12 simultaneous sockets of Modbus TCP. The standard 100BaseT Ethernet port allows multiple users to access meter data without any interface.

• 12 Simultaneous Sockets Of Modbus Over Ethernet Communication
• Multiple Sockets Means Multiple Users Or Software Systems Can Reach Meter Simultaneously
