Experimental results of ELF electric and magnetic fields of electric power systems in Bosnia and Herzegovina
Investigations of electric and magnetic fields on 400 kV transmission lines Tuzla-Visegrad, Sarajevo 10-Sarajevo 20, Tuzla-Ugljevik and 220 kV transmission line Kakanj-Zenica are performed. These transmission lines are important objects for operation of electric power system of Bosnia and Herzegovina. In the paper measurements of extra low frequency (ELF) electric and magnetic fields (EMF) of single 220 and 400 kV overhead transmission lines with flat conductor arrangement but with different horizontal distances between phases and different heights above ground are presented. These electric and magnetic field measurements are also compared with calculations results performed with two software programs (one commercially available and one developed by authors on the base of a solver). Also, in the paper the parameters influencing electric and magnetic fields measurements are investigated.
