The article deals with quality power grids in metallurgical industry. Nowadays the power grids are loaded by non-linear loads which cause distortion of voltage and current track. Thanks to this distortion the power grids are overloaded and its efficiency decrease. The expensive adjustments of power grids are necessary. This adjustments increase claims on investments and maintenance. In the article is described developed analytic system that is able detect and measure this distortion. Based on measured values the power grid in the factory can be analyzed and the improvement can be proposed.Keywords: Metallurgy, power grid, microprocessor, Fourier transform
