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.
II. Introduction
The research project is built around the Teridian 71M6513 Power Metering chip. The project involved working with a TDK Semiconductor Corporation (TSC) 71M6513/71M6513H Demo Board.
The Teridian 71M6513 is a highly integrated System On a Chip, SOC, with an MCU core, RTC, FLASH and LCD driver. Teridian’s Single Converter Technology™ with a 21bit 2nd order delta-sigma ADC, 6 analog inputs, digital temperature compensation, precision voltage
