The Yokogawa WT1800E Power Analyzer offers the ultimate precision and reliability for power measurements, suitable for a wide range of applications such as motors, inverters, electric vehicles, and renewable energy solutions. With ±0.05% accuracy and the ability to analyze harmonics up to the 500th order of a 50/60 Hz fundamental frequency, the WT1800E is an essential tool for engineers seeking to optimize advanced power measurement and energy efficiency.
With the ability to measure up to 6 inputs simultaneously, the WT1800E can perform more complex power analysis, ideal for measuring multi-phase devices such as inverters and motors. The 8.4-inch high-resolution screen allows the user to display up to six waveforms simultaneously and monitor up to 12 pages of measurement parameters. This makes the device particularly suitable for high-accuracy testing, such as electric vehicles and renewable energy sources.
The accuracy of the WT1800E is guaranteed over a wide range of voltages and currents, ranging from 15 mV to 1100 Vrms and from 0.1 mA to 5.5 Arms for the 5 A elements and up to 55 Arms for the 50 A elements. Higher currents are of course also possible in combination with a complete line of zeroflux sensors. All this ensures that accurate measurements are possible even at large phase shifts and high frequencies. The low power factor error of only ±0.07% of apparent power provides reliability even under difficult measurement conditions.
The Power Integration feature allows the WT1800E to integrate both positive and negative values, making it possible to accurately measure power consumption in devices that switch between standby and operating modes. This is particularly useful for grid connections and batteries, where both consumed and generated energy can be measured. The auto-ranging function allows the device to automatically adjust the measurement range when the input signal fluctuates.
The high-speed capture function can capture Sigma values for voltage, current and power up to every 5 ms without external synchronization or up to 1 ms with external synchronization. This makes the WT1800E highly suitable for applications where speed and accuracy go hand in hand.
The WT1800E is not only a powerful instrument for electrical power measurements, but also offers the possibility of harmonic analysis. With the optional /G5 and /G6 modules, harmonics up to the 500th order can be measured, which is essential for evaluating inverters, motors and UPS systems. This makes the device perfect for energy efficiency analysis and quality assurance in electrical networks.
For advanced users, the WT1800E also offers comprehensive motor evaluation functionalities, including measurements of rotational speed, torque, mechanical power, and synchronization speed. This enables detailed analysis and optimization of electric motor efficiency. Through the WTViewerE software, users can easily view, control, and download measurement data via their PC.
With extensive communication options such as USB, Ethernet and optional GP-IB, the WT1800E can be easily integrated into existing data networks for real-time monitoring and analysis.
The Yokogawa WT1800E is the perfect choice for engineers and researchers looking for an accurate, flexible and powerful measurement instrument for power and energy analysis.
