Nexus® 1450 Cyber Secure Power Quality Meter with Multiport Communication

Electro Industries’ Nexus® 1450 meter is a powerful power quality meter that provides accurate electrical energy measurements. It offers advanced capabilities for power quality analysis and determining electrical power reliability. The meter is a transducer base with a separate display. The transducer base retrofits to existing Electro Industries’ Nexus® 1250 and 1252 meters. The Nexus® 1450 power quality meter is ideal for existing switchboard panels since it can be installed without cutting panel doors. The separate display mounts into existing analog meter knockouts.

Multi-Gain™ Sensing Provides Superior Accuracy
EIG’s Latest Measurement Sensing Technology

  • Patented technology provides 0.06% energy accuracy throughout extended measurement range, from start up to full scale
  • Multi-Gain™ technology uses two sensors on the current inputs to determine the optimal sensing circuit for the highest accuracy measurement
  • Standard pickup range starts as low as 1 mA – high accuracy is attained at 25 mA
  • Multi-Gain™ metrology enables one meter to be used on both 5 A and 1 A secondary CTs
  • The meter should maintain high accuracy measurement throughout its installed life
  • The power quality meter meets ANSI C12.20 0.1 and IEC 62053-22 0.2S accuracy classes

Advanced Energy Meter
Supports Primary Metering Load Requirements

  • Full 4 quadrant metering, max/min recording with timestamp
  • Perpetual Time of Use
  • Transformer line loss compensation
  • Coincidental readings
  • Load aggregation/universal metering
  • Extensive logging with 8 logs of programmable historical profiles

Power Quality Monitoring and Analysis
Save Money by Improving Reliability

  • Certified to the highest international power quality standard – IEC 61000-4-30 Class A Ed. 3
  • Analyze power system health to reduce downtime
  • Collect power factor per circuit to correct worst scenarios
  • Monitor harmonics to assess the impact on equipment
  • Measure flicker and generate weekly EN 50160 power quality reports

  • Provides energy dashboard with real time voltage and current readings, detailed charts of energy usage over time, quadrant energy charts, and trending
  • Displays waveform event records and allows zoom and pan and overlay of voltage and current waveforms
  • Displays symmetrical components, phasor diagrams, flicker readings, status of high-speed digital inputs, and detailed information for accumulators and aggregators
  • Supplies meter and diagnostic information for meter health and status and enables firmware upgrade
  • Supports IEC 61850 file management

Resilient Cyber Security™
Prevent Attacks on Your Power System Data

  • Highly secure, 32 complex character passwords with 128-bit AES encryption
  • Password fail timeouts virtually eliminate brute-force hacking
  • An Admin and 10 customizable users
  • Four roles with customized user permissions
  • 256-bit digital firmware signature, to ensure firmware integrity when updating the meter’s firmware

Built-in CORE™ Log
Automatically Stores Meter Readings

  • The power quality meter uniquely uses an internal SQL database that automatically logs metering parameters
  • 142 metering parameters are logged at regular intervals
  • The CORE™ log ensures that most metering parameters are already logged – the power quality meter provides data without a complex configuration process

Advanced Communication and I/O
Six Standard, Simultaneous Communication Ports

  • Up to 32 simultaneous protocol connections
  • 4 independent serial ports – 3 RS485 and 1 RS485/RS232 selectable
  • 2 independent Ethernet ports – RJ45 and Fiber Optic, with separate IP addresses advanced port control, encrypted email on alarm, web server, and DHCP

IEC 61850 GOOSE Messaging and Distributed Fault Recording
GOOSE Cross Trigger Support

  • Unique distributed disturbance recording analysis improves substation reliability
  • Up to 16 user-programmed conditions to trigger system-wide waveform capture
  • Enables analysis of power quality events across the power system

Direct Retrofit with Advanced Remote Displays
Replace Older Meters without Panel Modification or Recertification

  • Transducer/remote display direct retrofit to older Nexus® 1252 meters makes installation cost effective
  • Remote displays retrofit to ANSI cutouts, so the power quality meter can be mounted in back of panel
  • P70N color touchscreen LCD display offers multiple pre-configured screens.
  • P40N+ LED display can act as a master to P41N+ Ampere and P43N+ Power displays, providing 3 panel displays on one connection powered by the meter. This is ideal for substation and power plant applications.
