When Measuring the Balanced Three-Phase Load and Displaying the Waveform, the Phase Angle of the Voltage Across Each Input Element Does Not Equal 120 Degrees

Optimize efficiency and ensure compliance with industry-leading power measurement. Yokogawa analyzers deliver unmatched accuracy in watts, power factor, harmonics, and efficiency, so you can design greener systems and validate performance with confidence.

With 0.02% accuracy and 1MHz bandwidth, the WT3000 delivers where the highest precision measurements are required. It is the industry standard for R&D work on inverters, motor drives, lighting systems and electronic ballasts, UPS systems, aircraft power, transformer testing, and other power conversion devices.

The WT1800 Power Analyzer offers maximum flexibility with up to six wattmeter elements, high bandwidths, simultaneous high speed digitizing, and wide voltage and current ranges. Although this model is still available, the newer WT1800E offers higher accuracy.
