2 kWatt Harmonic Analyzer Prototype Using Discrete Fourier Transform Method

We knew that there are so many power harmonic analyzer in the market. Much of them are from well known company and commercialize that bring the engineer found it easily. In this paper we just want to proclaim that Indonesian engineer has capability to develop such that system. That is why we want to introduce a 2kWatt harmonic analyzer prototype using Discrete Fourier Transform (DFT). The prototype is built up using ATMega 32 Microcontroller. Fourier transform mechanism is made and then plant in the microcontroller that is functioned as a processor. This controller is chosen, because it has some advantages, one of it is an internal ADC that give the user easily to convert from analog unit into digital one. After prototype was completely finished, it was tested with 13 different types of load and compared with the well know product of Fluke 41B Power Harmonics Analyzer. From that test, we can deliver some conclusion are the error average of voltage THD is 1.8% and error average of current THD is 1.96%
