The electric power quality evaluation is a complex measuring task requiring the use of a system with appropriate metrological properties. Such system includes a set of selected and determined quality measures implemented in the measuring system that records the measuring results preliminarily processed. Another stage is the final statistical processing representing the foundation for the ultimate concluding. The concluding task is to find whether the quality standards are maintained and to indicate the possible reasons for underestimating the quality.
