The Fluke 1760 Three-Phase Energy Logger is a Class-A power quality analyzer and energy logger engineered to capture and record comprehensive data across three-phase power systems. It detects transient events, voltage deviations, harmonics, and power disturbances with high resolution, while maintaining full compliance with IEC 61000-4-30 Class-A for accurate, repeatable measurements in utility, industrial, and medium- to low-voltage applications.
