The appearance of the power frequency overvoltage in the transmission network
2013 International Conference-Workshop Compatibility And Power Electronics, 2013High voltage transmission network in Bosnia and Herzegovina registered significant values of power frequency overvoltages which lasted quite long. This paper identified levels of temporary overvoltages on the basis of measurement results in an annual period during 2010 in specific points of 220 kV and 400 kV network.
