Abstract: This study proposes a prototype of harmonic analyzer that can be synchronized with Android. The prototype is used to measure and monitor harmonics in the power systems as well as micro grid system. The prototype of Android based Low Cost Harmonic Analyzer (ALCHA) is constructed by using current sensor, microprocessor, data base and Android Software. The advantage of ALCHA is very cheap comparing to commonly harmonic analyzer in the market. ALCHA utilizes available components on the market with affordable price and also, utilizes open source software. In this study, the observation is focus on harmonic 3rd, 5th, 7th and 9th and Total Harmonic Distortion (THD) that referring to IEEE 519 standard. Based on experiment results can be proof that ALCHA has capability for detecting harmonics that occur both in the power system and in the micro grid system. Standard deviation of ALCHA compared to laboratory scale harmonic analyzer is around 1.4%.
