    The ideal power system, voltage waveforms delivered to the customer equipment and the resulting current waveform is pure sinus wave. Power Factor occurred due to the high percentage of current harmonic content (THD) on the power system. This causes the decrease in power quality and a very significant losses, especially on an industrial scale power system. Thus, creation of DESIGN OF PORTABLE POWER ANALYZER MODULE FOR ANALYZING THE POWER FACTOR for this final project, expected to evaluate the effects of distortion of voltage and current waveform non-sinusoidal loads caused by non-linear in the electric power system. This can be done through measurement of harmonics contained in the wave. By using ATMega 32 as controller and as an internal ADC analog signals to digital converter, the system becomes more simple. Digital signals are processed in the Microcontroller based on harmonic components using the Discrete Fourier Transform (DFT). Results of the evaluation process is displayed on the LCD graphic G12864C the value of Vrms, IRMS, Power, Power Factor and graph voltage and current. From testing the system as a whole, shows that the system works well, as evidenced when tested with resistive loads, inductive and capacitive devices can display the value of the above information. Keyword : THD, DFT, ADC, power factor
