The Fluke 438-II Power Quality and Motor Analyzer uses innovative algorithms to analyze not only three-phase power quality but also torque, efficiency, and speed to determine system performance and detect overloaded conditions, eliminating the need for motor load sensors. It will also analyze the motor's efficiency and mechanical power under operating load conditions.
The Fluke 438-II analyzer provides analysis data for both the electrical and mechanical characteristics of the motor while it is in operation. Using proprietary algorithms, the 438-II measures the three-phase current and voltage waveforms and compares them against rated specifications to calculate motor mechanical performance. The analysis is presented in simple readouts, making it easy to gauge the operating performance and determine if adjustments are needed before failures cause an operational shut down.
