Statistical Analysis of Voltage Sags in Distribution Network According the EN 50160 Standard : Case Study

The paper will present results of power quality measurements in distribution network in Slavonia and Baranja region of Republic Croatia. European standard EN 50160 gives the main characteristics of the voltage, supplied by the public distribution network, at the customer’ s supply-terminals in public low voltage and medium-voltage electricity distribution networks under normal operating conditions. Measurements were performed on transformer stations in distribution network with different type of consumers of industrial (paper, food and cement industry), domestics and public sector. The latest state-of-the-art power network analysers (LEM Memobox 800, 808 and Topas 1000, supported by powerful software) were used for measurements. A measurement period used for each consumer was a one week, according to the European EN 50160 standard.
