Nexus® 1500+

Next Generation Power Meter for Critical Energy Circuits

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 me-

tering 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.

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

System Events Logging

The unit provides extensive usage information for detection of

unauthorized access. The unit records:

• Resets

• Programming changes

• Password access changes

• Time changes

• Power up/down

• Change of Firmware

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 accumu-

lator 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.

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.

Class A Power Quality Recorder

EIG’s Nexus® 1500+ meter is one of the industry’s premier fault and

voltage disturbance recorders. This instrument captures and stores a

comprehensive picture of the history of voltage reliability and power

quality events, for detailed and extensive forensic engineering analysis.

The Nexus® 1500+ meter offers a multitude of power quality

functionality that helps the user identify power quality problems, including

harmonics, sags, swells and transients. Power quality features include:

IEC 61000-4-30 Class A Power Quality Meter:
