In 1997 cooperation began between the Faculty of Electrical Engineering and Computer Science power company CEZ on a joint project that involved monitoring selected voltage quality parameters. Over course several years measurements were carried out at 59 points distribution system low (LV) level their supply nodes medium (MV) high (HV) levels, which constituted more than 100 measured points. The continued until 2012 (with one-year break in 2009) with total scope five cycles three-year measurements. last phase was focused, inter alia, evaluation 15th 21st harmonics. From 2013, focused again flicker localities occurrence elevated levels this parameter. At these sites, for two weeks spring autumn period three years. basis evaluating parameters is standard EN 50160.
