Product Overview

The ANR96 is a panel‑mount multifunction electrical network analyzer built for three‑phase power‑system monitoring within industrial facilities, power‑generation plants and utility substations. It acquires voltage, current, power factor, active/reactive power and energy readings, alongside harmonic‑distortion analysis up to the 31st harmonic, delivering comprehensive visibility over grid‑quality conditions. The integrated backlit graphic LCD and five‑button keypad enable local parameter setup, measured‑value browsing and alarm‑threshold configuration without external software.

This device addresses key electrical‑monitoring challenges: unified multi‑parameter power‑network measurement, harmonic disturbance detection, and seamless data export to DCS/SCADA platforms for energy‑management workflows. Isolated communication ports reduce ground‑loop interference over long‑distance field‑bus wiring. Plant‑electrical engineers, energy‑management technicians and system‑retrofit integrators benefit most. It fits standard 96×96 mm panel cutouts, supports optional digital I/O modules for pulse‑output energy pulsing and alarm‑relay triggering, and serves as drop‑in spare hardware for legacy power‑monitoring installations across process‑industry and power‑plant sites.

Key Application Notes

• Accepts voltage‑transformer and current‑transformer secondary signals; not designed for direct high‑voltage connection
• Base unit provides two opto‑isolated digital inputs; additional I/O and communication functions require option add‑on boards
• Internal backup battery preserves accumulated energy counters and configuration parameters during supply outages
• Compliant with IEC 61010‑2 safety standards for industrial electrical‑measurement instruments
• Measurement data can be logged remotely via Modbus‑RTU/TCP for energy‑audit and power‑quality‑analysis purposes
• Front‑panel keypad access can be password‑locked to prevent unauthorised parameter modification
