Abstract Hourly measured high voltage values in power network 400 kV, 220 kV and 110 kV are presented in this document. Higher values of voltage in relation to nominal voltages, maximum voltages and their time duration have been identified in observed time period. Maximum voltage values are compared with duration of higher voltages for available time period of measuring from 2014 to 2016. This document presents the results for power flow analysis, charging of reactive power and voltage conditions on transmission lines. A review of the operational state of the power system in Bosnia and Herzegovina is given in specific maximum and minimum consumption regime. In addition, a comparison of voltage values being calculated and measured was made.
