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. |

Power Quality Recording |

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
