Yokogawa Test & Measurement has launched the WT1800R Series, a power meter designed to meet the growing demand for highly accurate power measurement in industries such as electric vehicles (EVs) and power electronics.
With a focus on improving energy efficiency and optimizing motor control parameters, this series builds on the capabilities of its predecessors, the WT1800 (released in 2011) and the WT1800E (2016), while incorporating new features to support advanced motor evaluation.
EV application features
The WT1800R guarantees a power accuracy of ±0.1%, making it ideal for evaluating EV high-efficiency motors and power systems. It’s equipped to handle a wide dynamic range, ensuring precise measurements even with significant current variations.
Additionally, its math functions allow for the calculation of motor parameters, such as Ld and Lq values, critical for motor control optimization. By integrating with waveform measuring instruments like the DL950 data logger via the IS8001/IS8002 software platform, the WT1800R enables synchronized power and waveform measurements to identify efficiency losses during continuous motor operation.
High-current measurements
The WT1800R offers improved usability for high-current measurements with an optional power supply for current sensors, eliminating the need for external connections. A new accessory, compatible with the CT1000S ac/dc split core current sensor, simplifies installation without requiring cable disconnection, streamlining the testing process for EV motors and other high-power applications.
Designed to enhance power conversion efficiency and support high-precision testing, the WT1800R Series addresses the specific needs of EVs and other power-intensive applications, enabling manufacturers to achieve greater energy savings and performance optimization.
