Yokogawa Test & Measurement Releases WT1500 Precision Power Analyzer
- Meeting the power measurement needs of high-voltage xEV and renewable energy applications -

Yokogawa Test & Measurement Corporation announces the release on August 19 of the WT1500 Precision Power Analyzer as a new addition to the WT series. The WT series power analyzers are widely used as essential measurement instruments for the development and performance evaluation of powertrains for electric vehicles (xEVs) and renewable energy-related equipment. The new WT1500 features the series’ first 2000 V DC input voltage capability and industry-leading measurement accuracy. It also incorporates a space-saving design for ease of use in test environments, resolver signal^*1 input support, and multi-unit synchronization^*2. These features enable the WT1500 to meet evolving measurement needs in applications with higher voltages and increasing system complexity.

Development Background
Continued advances in xEV technologies and the growth of the renewable energy market is accelerating demand for evaluation, testing, and production capabilities built around high-voltage equipment. However, when measuring voltages exceed 1500 V, conventional power analyzers require dedicated high-voltage dividers, which can affect measurement accuracy and complicate wiring and equipment installation. In addition, measuring motor efficiency in xEV applications has traditionally required power signals and resolver signals to be measured separately and synchronized later on a PC. Combined with the challenge of fitting measurement instruments into conventional rack-mounted setups or limited desktop test environments, these requirements have made testing and evaluation processes complex and time-consuming.
