Abstract

This thesis is focused on frequency analysis of power grid in industry companies. The aim of the paper is measure and compute frequency spectrum of power grid by FFT algorithm programmed in 32bit microprocessor. Frequency spectrum is as quality indicator transferred by communication interface to the personal computer where the spectrum is graphically displayed for easy interpretation and analysis. Numerical methods are part of this paper when own numerical filters are used for removing unimportant data. One of the outputs of this paper is software which executes mentioned operations.
