Nexus^® 1450

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.

Supports Primary Metering Load Requirements

• 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.
• Record waveforms at 1024 samples/cycle.
• Provides PQ reliability indices, including CBEMA and SEMI F47.

Provides Waveform Analysis over the Internet

• 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.

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.
• Sealing switch and physical seals prevent remote hacking or tampering.

Automatically Stores Meter Readings

• The power quality meter uniquely uses an internal SQL database that automatically logs metering parameters.
• 172 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.

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.
• Communication protocols include Modbus RTU, Modbus ASCII, Modbus TCP/IP, DNP3 Level 2, IEC 61850, IEC 61850 GOOSE, SMTP, SNTP.
• RS485 ports support RTU Master.
• 8 built-in digital status inputs, 2 standard pulse outputs.
• Multiple external I/O modules are available: digital and analog outputs, digital inputs, digital relay outputs, digital solid state pulse outputs.
• Up to 256 total points of I/O.

Supports Substation Automation

• IEC 61850 Edition 2.
• Either Ethernet port can be configured as an IEC 61850 protocol server.
• Up to 6 simultaneous MMS clients.
• Buffered and unbuffered reports.
• GOOSE messaging.
• Multiple pre-programmed logical nodes for power and energy values, power quality, and high-speed digital inputs.
• Web server supports downloading and uploading of CID files.

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.
• See how EIG’s Distributed Fault Recording works.

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.
