Mastering Precision: The Power of Test & Measurement
Steve Rogerson highlights the release of Yokogawa’s new precision power analyzer, the WT5000, which boasts a world record measurement accuracy of ±0.03%. This tool is expected to significantly aid the electric vehicle (EV) industry, which still faces challenges such as range anxiety—drivers worrying whether their EVs will have enough power to reach their destinations—and long charging times.
To make EVs more viable, improvements in powertrain efficiency are crucial, and this is where advanced test and measurement equipment like the WT5000 comes into play. Anoop Gangadharan, Yokogawa’s product marketing manager in Europe, emphasized the importance of precision for engineers, describing them as the problem-solvers of today’s challenges.
At the WT5000’s launch, Gangadharan noted that engineers need reliable data to make informed decisions and avoid product recalls, especially in conditions that are constantly changing. He presented the WT5000 not just as a power analyzer but as an extensive power management platform. Due to its modular design, users can add more capabilities over time to keep up with advancing technologies.
The WT5000 is not just for the automotive industry; it is also applicable in renewable energy, home and office appliances, and industrial equipment. Its seven swappable input modules allow for diverse applications, such as measuring up to four motors simultaneously in automotive settings. It can assess various parameters like torque, rotation speed, and efficiency of multi-phase motors.
Gangadharan shared his excitement about the booming electric vehicle market, highlighting it as one of the fastest growing segments for Yokogawa. Yet, consumer adoption has been slower than expected due to issues like range anxiety and lengthy charging times. He stressed the need to cut charging times to under 30 minutes to spur broader EV adoption.
Furthermore, improving powertrain efficiency is vital. The WT5000’s high accuracy and ability to measure multiple motors simultaneously help in this aspect. With capabilities such as evaluating six-phase motor systems and harmonic analysis of inverter signals, the WT5000 stands out in addressing these needs. Its modular design, wide input range, and sensor compatibility make it a versatile and powerful tool for the evolving automotive standards.
In summary, Yokogawa’s WT5000 offers superior measurement accuracy and modular flexibility, making it a critical asset for engineers working to enhance the efficiency and reliability of electric vehicles and other applications.
