Description

The Fluke 1777 Three-Phase Power Quality Analyzer is a high-performance diagnostic instrument engineered for detailed analysis, logging, and troubleshooting of electrical power systems in industrial, commercial, and utility environments. Part of Fluke’s 1770 Series, it simplifies power quality studies by combining automated measurement capture with advanced waveform analysis, enabling users to gather accurate and comprehensive data with minimal setup effort.

Designed to measure more than 500 power quality parameters, the 1777 provides real-time assessment of voltage, current, frequency, power, dips, swells, harmonics (both up to 30 kHz and detailed integer harmonics), flicker, and transient events. Its advanced transient capture capability — with sampling rates up to 20 MHz — allows the analyzer to record high-speed voltage disturbances in fine detail so that intermittent or fast occurrences can be identified and addressed.

Featuring a large, high-resolution display (often touchscreen) and an intuitive user interface, the Fluke 1777 makes data review and navigation straightforward, even in complex three-phase systems. The instrument can be powered directly from the measured circuit, reducing the need for external power supplies in the field, and includes a rugged ergonomic design to withstand industrial environments.

The analyzer supports extensive data storage via large internal memory (typically with a microSD card), capturing long-term logs as well as triggered events. After collection, power quality data can be downloaded and analyzed on a PC using companion software, enabling in-depth trend analysis, customizable reporting, and compliance verification to international standards such as IEC 61000-4-30 Class A, EN 50160, and IEEE 519.

With its combination of automated measurement capture, high-speed sampling, and powerful analysis tools, the Fluke 1777 helps electrical professionals identify root causes of power disturbances, optimize system performance, and verify compliance with industry power quality standards.
