A comprehensive review of split core current transformers and explanation of their principles of operation, design considerations, advantages, disadvantages compared to other CT technologies, and applications.
Maximum torque per ampere (MTPA) is an optimization strategy for the control of electric motors and drives that employ field-oriented control (FOC), particularly with electric vehicles (EVs) and industrial automation applications. The goal of MTPA is to achieve the maximum possible torque output from a motor for a given current input.
Designing an instrumentation system for high current measurement requires careful consideration of the trade-offs associated with each type of sensing device. The purpose of this application note is to help engineers understand the sensing choices available and the corresponding trade-offs with each technology.
In this application note you will learn when and how to use different methods to connect a current transformer to a power analyzer.
Maximum power point tracking (MPPT) charge controllers play a crucial role in the optimization of renewable energy system efficiency and performance. Through dynamic tracking of a renewable energy source’s maximum power point, an MPPT controller enables more efficient energy harvesting, faster charging, and adaptability to changing environmental conditions.
The right tool to measure power in complex EV systems is a purpose-built power analyzer that captures three core parameters—voltage, current and power—as well as a few very important additional parameters (depending on what system you are testing) that contribute to understanding the efficiency and overall system performance.
The impedance of the 366924 and the 366925 BNC cable is 50 Ω.

I’ve been using Yokogawa Test&Measurement instruments for power measurement and analysis for several years and they always get the job done. They provide extensive and thorough documentation for their equipment and their drivers are very handy. Features like screengrabs of test results for easier sharing and the remote interface (which minimizes the time we spend having to automate tests) have proven to be incredibly helpful. My team needs instruments that are well documented, easy to use, and reliable. Yokogawa instruments check all these boxes.

It’s not an exaggeration to say I owe a good bit of my career success to Yokogawa Test&Measurement. By using their ScopeCorders that combine the best parts of an oscilloscope and DAQ, projects that once took weeks across multiple instruments suddenly only took a few hours with just one instrument. The impact on what I could accomplish really was quite remarkable, and my ability to accurately complete projects in record time made me look incredible. No matter how complex or convoluted the task, the ScopeCorders never fail to easily handle anything I throw at them. They’re amazing instruments and I tell others about them every chance I get. —Kenneth Shoemaker, Automotive Industry Consultant/Owner at Panama Prototypes

When I started with my company almost 20 years ago, Yokogawa Test&Measurement instruments were already in use and the engineers had no intention of switching. In fact, we still routinely use some of the older instruments because, well, they just work! The equipment doesn't really become obsolete, and they support their instruments as long as is feasible, which ultimately saves us money. Even so, as things change in our industry Yokogawa adjusts to meet those changes. From our sales representative through technical support and more, I can count on the Yokogawa team to really listen and work with us to provide a specific solution for unique problems.

Product Overviews
The current sensor element for the Yokogawa Test&Measurement WT5000 Precision Power Analyzer is ideal for applications requiring a current transformer for high-current measurements. The internal DC power supply simplifies preparations before measurement, requiring only a connecting cable and eliminating the external power supply.
The WT5000, an industry-leading power analyzer, features seven field-removeable elements, 10 MS/s, 1 MHz power bandwidth, 18-bit resolution, and 0.03% basic power accuracy. Yokogawa Test&Measurement continues to innovate on the platform, enabling /D7 data streaming, /G7 harmonics, and flicker analysis.
The new current sensor element replaces the traditional current inputs and includes a sensor input terminal with integrated ±15V power supply, eliminating the need for an external power supply. The isolated voltage terminals remain the same as the 5A and 30A elements.
