GE Multilin 735-5-5-HI-485 Digital Power Quality Meter Substation

Product Description

Overview

The 735-5-5-HI-485 from GE Multilin is a multifunctional digital power meter and substation monitoring unit. It combines high-precision metering, power quality diagnostics, and feeder protection into a single, compact device. This model supports both industrial and utility-scale applications, making it ideal for revenue-grade energy measurement and monitoring of harmonics, voltage sags, and swells.

Performance Highlights

Revenue-Grade Measurement

• Accuracy Class 0.2%: Meets ANSI C12.20 and IEC 62053-22 standards for high-precision energy billing

• High-Speed Sampling: Up to 1024 samples per cycle capture transient events accurately

• Measures phase and neutral currents with 5A CT inputs

Power Quality Monitoring

• Harmonic Analysis: Tracks individual harmonics and Total Harmonic Distortion (THD) up to the 63rd harmonic

• Voltage Event Capture: Automatically records waveforms during sags, swells, or interruptions

• Flicker Compliance: Monitors voltage flicker according to IEC 61000-4-15

Data Logging & Event Recording

• Trend logging of Watts, VARs, Volts, and Amps over time

• Sequence of Events (SOE) storage with millisecond timestamping

• Load profile capture to support energy management and peak demand analysis

Communication & Integration

• RS485 Port for daisy-chaining meters to SCADA or Building Management Systems

• Protocol Support: Modbus RTU and DNP 3.0

• Front-port interface allows local configuration via laptop

Industrial Durability

• Power Supply (HI): 88–300V DC or 85–265V AC for substation compatibility

• Rugged design withstands harsh EMI environments typical of substations

• Operating Temperature: -40°C to 70°C

Feeder Protection Features

• Phase and ground timed overcurrent protection

• Phase and ground instantaneous overcurrent protection

• Diagnostic lockout and blocked instantaneous trip support for autoreclosure

• Standard outputs: main trip, auxiliary trip, relay service
