Fluke 1777

Fluke 1777 – Overview

The Fluke 1777 is a rugged, high-performance three-phase power quality analyzer designed to simplify diagnostics and long-term monitoring of electrical systems. It captures a wide range of power parameters, fast transients up to ±8 kV, detailed harmonic content to 30 kHz, and offers both live meter mode and long recording/logging functionality. It's built for field-use, with solid safety ratings and versatile connectivity options.

Key Features

• Three-phase + neutral voltage and current inputs

• Captures high-speed transients up to ±8 kV

• Harmonic analysis up to 30 kHz

• 24-bit synchronous sampling; automatic scaling for voltage & current sensors

• Supports common power topologies (wye, delta, split phase, open delta, etc.)

• Multiple log and record modes with large memory and micro-SD support

• Live on-screen data: V, A, Hz, power, dips, swells, harmonics

• Powerful analysis/reporting via software for compliance (EN 50160, IEEE 519, IEC 61000 series)

Technical Specifications
