BOBBIE JO MEREDITH,
Mrs. Meredith is currently a graduate student, Computer Engineering Technology major in the Department of Engineering Technology and Industrial Studies at Middle Tennessee State University. She earned her BS degree in Computer Engineering Technology with minor in Computer Science from MTSU in 2005. She is currently working as an Electronics Test Engineer for Schneider Electric, Power Monitoring and Control Division. Her interests include the design, building, programming, and testing of microprocessor and microcontroller based systems.
SALEH M. SBENATY,
Dr. Sbenaty is currently a Professor of Engineering Technology at Middle Tennessee State University. He received the BS degree in EE from Damascus University and the MS and Ph.D. degrees in EE from Tennessee Technological University. He is actively engaged in curriculum development for technology education. He has written and co-authored several industry-based case studies. He is also conducting research in the area of mass spectrometry, power electronics, lasers, and instrumentation.
JASON THURMOND,
With more than a decade of engineering and management experience, Jason Thurmond has developed a key sense of what it takes to develop Power Quality Analyzers and Power Metering equipment. Jason presently serves as Engineering Manager for Schneider Electric’s Power Monitoring and Control organization. He holds a Bachelors of Science in Computer Engineering from Middle Tennessee State University. He has been involved in evaluation and implementation studies for several IEC Power Quality and Safety standards and has multiple patents related to Power Monitoring devices.

Designing, Building, and Testing an Advanced Industrial-Grade Three-Phase Digital Power Meter
I. Abstract
The current paper describes the design, construction, and testing of an advanced digital three- phase power meter for industrial applications. The project is the result of a very close collaboration between the author, a senior Computer Engineering Technology major, her faculty advisor at Middle Tennessee State University (MTSU), and the design engineers at the Power Logic Group of Square-D, a Division of Schneider Electric in LaVergne, Tennessee. At the time of writing this paper, the author was completing her Internship at Square-D, where she was gaining the hands-on experience necessary for a successful employment after graduation and learning state-of the-art and real-world applications. The meter initial requirements include the measurements of AC voltages in the range from 0 to 55 VRMS and currents in the range from 0 to10 A per phase. In addition, the meter should be capable of measuring power (real, reactive, and apparent) and energy consumption per phase and total. The meter should also have an output pulse at the TTL level, with a set pulse weight. The output is for the total kW.hr and kVAR.hr. The meter also takes four-pulse inputs (from devices developed by Square-D), the result of converting 18-36 V to the TTL level, and display the four inputs on the onboard display. The above-mentioned data should be displayed on a seven-segment LCD display. The design, building, and testing of the above-specified power meter is presented. The research also reports on the ease of use, development tool quality, code efficiency, and other significant characteristics of the TDK development board. Discussions of the results and the benefits of this collaborative project are also presented.
