Introduction
The Nexus® 1500+ meter is designed to be a primary and testable
revenue meter that additionally provides advanced power quality analysis
functions. It records every aspect of electrical power, including power
quality and transients, and gives you access to this information both in
real time and through reports on the quality of the electrical circuit in
compliance with the IEC 61000-4-30 Class A and EN 50160 international
standards. In this way, the Nexus® 1500+ meter provides you with a
comprehensive picture of your circuits’ power usage and reliability.
The Nexus® 1500+ meter’s capabilities insure that essential data is
captured and stored, so that critical information about important electrical
circuits is not lost. Designed with superior processing power that lets it
measure energy usage precisely, large amounts of memory for recording
events, and advanced power quality reporting compliance, the Nexus®
1500+ meter is the clear choice for your applications where critical metering is an absolute necessity, be it for power utility, industrial, or other
critical metering usage.

Highly Accurate Energy Metrology
The Nexus® 1500+ meter incorporates one of the most advanced
metrologies available for measuring energy. Providing highly accurate
measurements exceeding the ANSI C12.20 (0.2 Class) standard and the
IEC 62053-22 (0.2S Class) standard, the 1500+ provides an Energy
Class accuracy of 0.06%, with typical shipping accuracies of 0.02%.
Additionally, the meter has a highly accurate front panel test pulse that
lets you test on one pulse at low pulse weight, which you can use to
quickly determine accuracy. The meter also features a new precision real
time clock that offers accuracy of 3.5 ppm, or less than 10 seconds per
month drift.
Typical Accuracy over Current Range

Typical 0.02% Accuracy over Full Range
Note that typical accuracy is 0.02%; however, the meter specification should be
consulted for accuracy details.

New Constant Calibration™ Architecture Increases
the Stability of Measurement Accuracy
The Nexus® 1500+ meter improves on existing Nexus® architecture
by providing one of the best auto-calibration methods available. Earlier
Nexus® models relied on AccuMeasure™ technology that auto-calibrated
the meter every 12 hours or 5 degree temperature change. Constant
Calibration™ architecture improves significantly on this, by providing
considerably faster, ongoing auto-calibration.
With Constant Calibration™ architecture, the meter utilizes a separate
calibration channel to calibrate the incoming signal in real time every
10 seconds, thereby insuring that the meter experiences minimal drift in
accuracy over time and temperature. With this auto-calibrating circuit,
right out of the box the Nexus® 1500+ meter will stabilize its readings
within 10 seconds. This means you no longer have to wait for the meter to
stabilize in temperature to achieve optimal accuracy. With Constant
Calibration™ architecture, the meter will hold its accuracy throughout
its operation range. Once the meter is tested, it will maintain the precise
accuracy even if the operating conditions are less than ideal.

Advanced Revenue Meter for
Primary Loads
The Nexus® 1500+ unit is a primary revenue meter designed to be used
for any important applications. In addition to highly accurate energy
measurement, the meter features:
•

Full 4 quadrant metering

•

Energy load profiling: log virtually unlimited historical trending

•

Time of Use perpetual calendar that supports multiple tariffs

•

Transformer and Line Loss compensation: for both iron and
copper and total substation losses

•

CT and PT compensation: correct for errors in current and voltage
transformers

•

Coincidental readings: e.g., PF or VARs at time of Peak Demand,
to identify number of capacitors needed, peak inefficiencies, etc.

•

Load aggregation/universal metering: pulse inputs can be used to
aggregate or accumulate different loads; utility products such as
gas and water can also be accumulated

Test Mode and Energy Presets
The Nexus® 1500+ meter offers a Test Mode for testing meter accuracy.
Test Mode allows the meter to be tested for watt-hour and VAR-hour
accuracy without affecting the stored readings. Using Test Mode, users
can verify the meter’s readings over the lifespan of an installed meter
without having to reset energy or disturb the load profiling and
demand recording.
The Energy Preset feature allows a user to program the energy accumulator values upon exiting Test Mode. This lets the user compensate for
accumulations missed during testing time, or easily swap a new meter for
a meter being replaced.

System Events Logging
The unit provides extensive usage information for detection of
unauthorized access. The unit records:
•

Resets

•

Time changes

•

Programming changes

•

Power up/down

•

Password access changes

•

Change of Firmware

Perpetual Time of Use for Complex Metering
The Nexus® 1500+ meter uses a perpetual Time of Use (TOU) calendar
that only needs to be set up once. The TOU implementation allows the
user to set up multiple tariffs to meet any contractual obligations. It also
allows the user to customize any energy parameter for TOU. The 16
available TOU registers can be configured not only for TOU built-in energy
readings, but also for any stored data from pulses or RTU Master readings
that might need TOU functionality.
