This paper underlines the importance of permanent power quality measures in distribution network and proposes the interval and event (change in topology) based time schedule of measurements in depth of the network. Some nodes do not need to be measured during 7 days according to EN 50160 to realize that there are great problems to solve in a new technical resolution. Similar to the trend of entropy, true harmonic distortion (THD) in distribution power system is expected to increment, so - momentary measures are sufficient to mark subparts of the power system with unsatisfactory level of power quality. The most important problem to solve is to mark the consumer's generated harmonic distortion. Importance and benefit of the proposed method is to save the time needed to name causes of disturbances (consumer or device) and to anticipate the repairing of power quality. A new flow-chart is suggested for recognition of the consumer THD generation amount. Also, it leads to better technical or managing decision making during maintenance and investment planning activities. Further results of systematic planned measures that need to be done along the distribution power network, will enable global recognition of THD causes in network and simultaneously give exact solutions.
