In the below linked paper published on ResearchGate, a researcher from Cal Poly San Luis Obispo uses a Yokogawa Test&Measurement WT310 Digital Power Meter to review the power, current, and voltage measurements of a microinverter system.
The WT300 offers high performance and high reliability in a compact package with excellent price value, making it ideal for multiple applications from R&D to manufacturing test. It is the fifth generation of Yokogawa's value series power meter, and the world's best selling power meter.
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.
Yokogawa's Power Analyzer software manages numeric, waveform, and harmonic data measurements. It enables data logging and instrument configuration from your computer.
The WTViewerFreePlus software captures measured numeric values, harmonic values, and waveform data. Users can view and save data on a PC using USB, GPIB, RS-232, or Ethernet.
