To detect the harmonic produced by arc furnace and other high-power machines,based on analyzing and researching the tech-nical of electric harmonic measurement system at present,a new method which adopts a high speed and precision ADC chip and ARM + DSP truss to construct a new electric harmonic measurement system is designed,and also Qtopia core and touch screen are used as graphic library to develop graphic interface,and as input respectively and have quick response to any action. This method is not only to provide user graphic display,store,further communication and data diagnose but also to have high precision,function expandable and ability to detect 60 times harmonic wave.
