POWER QUALITY MEASUREMENT BY DEVELOPMENT OF LOW COST POWER ANALYZER

Power Quality is an important issue in a power system. This paper describes to develop an instrument by can measure power quality.Power analyzer which measure power flow in desired circuit by measuring actual value of current, voltage, power factor and harmonics with fundamental wave. In this paper we have to specify procedural development of a prototype an instrument to compute the power quality. To measure signals from plug-in-data power spectrum analyzer tools have adopted due to its rigidity, robustness and easy to use. FFT signal analysis computation which perform on power spectrum tool to measure frequency content of stationary & transient signal of noise content. To show the achievability of proposed work in this paper we have used Ardinuino-uno with FFT signal analysis to develop power analyzer. The measurement under test result is compared with standard instruments provide effectiveness of circuit model work.
