Description
Overview
The Fluke 1777 Three-Phase Power Quality Analyzer is a professional power quality troubleshooting, logging, and analysis instrument designed for electrical engineers, maintenance teams, facility managers, commissioning specialists, and industrial service providers. It belongs to the Fluke 1770 Series, a family of three-phase power quality analyzers built to simplify power quality studies, capture critical events, and provide clear measurement data for corrective action planning. Fluke describes the 1770 Series as combining automatic measurements, guided setup, straightforward operation, and a simplified reporting platform for power quality troubleshooting and logging.
For industrial and commercial electrical systems, intermittent power quality problems can be difficult to diagnose because events such as dips, swells, interruptions, harmonics, inrush current, and fast transients may occur unexpectedly. The Fluke 1777 helps users capture and review these events with high-speed transient recording, harmonic measurement, and power quality logging. According to Fluke, the 1770 Series can capture fast transients up to 8 kV, harmonics up to 30 kHz, dips and swells, voltage measurements, current measurements, and power measurements.
The Fluke 1777 is positioned for advanced power quality applications where high-speed transient visibility is important. Fluke states that the Fluke 1777 has 20 MHz sampling capability for capturing the fastest transients in high detail, while the broader 1770 Series also provides large-screen viewing of waveforms, transients, and higher-frequency harmonics. This makes the Fluke 1777 suitable for users who need a field-ready analyzer for troubleshooting unexplained equipment failures, evaluating electrical system health, documenting power quality issues, and supporting preventive maintenance programs.

Applications
The Fluke 1777 Power Quality Analyzer is designed for advanced electrical power quality troubleshooting and analysis in industrial, commercial, utility, and facility environments. It can be used for power quality studies, energy surveys, load studies, harmonic surveys, mains signaling monitoring, nuisance circuit breaker tripping investigations, power utility power quality surveys, and discovery of equipment failures caused by transient events. Fluke’s application comparison specifically lists energy surveys and load testing, harmonic surveys, nuisance circuit breaker tripping, electric utility power quality surveys, discovery of equipment failures caused by 8 kV microsecond transients, and discovery of equipment failures caused by 8 kV nanosecond transients for the 1777 model.
Typical buyers include maintenance departments investigating recurring downtime, electrical contractors documenting site power quality, commissioning teams validating electrical installations, and engineering teams comparing measured data against standards. With Energy Analyze Plus, users can generate reports aligned with standards such as EN 50160, IEEE 519, GOST 33073, and IEC 61000-2-2, and export data in formats including PQDIF, NeQual-compatible format, or CSV.
