A Study on the Data Aquisition System for Power Quality Analysis of Load Equipment

In order to analyze voltage, current, electrical power, harmonics and so on of electrical load equipments, electrical power analysis by real measurement rather than mathematical modeling is necessary, and plan of countermeasure for efficient management, energy frugality and accident prevention of electrical equipments using it is possible. Especially, electrical power analysis by real measurement is indispensable in order to consider countermove of harmonic occurred by nonlinear load. So, in this paper, we developed DSP(Digital Signal Processor) based low price date aquisition system, and verified it's ability by performing measurement and analysis of electrical power and harmonic in the real power system.
