The Fluke 430 Series II three-phase power quality analyzers measure energy waste in electrical systems and quantify its cost. The tool helps facilities reduce electrical power consumption and improve the performance and lifespan of electro-mechanical equipment by providing the ROI justification to mitigate power quality distortion. The 430 Series II can also simultaneously measure the input and output power of inverters in solar systems, wind turbines, and uninterrupted power supplies.
