Electromagnetic field impact on 150 kV Raha-Baubau transmission line

Abstract

The construction of 150 kV transmission line in Southeast Sulawesi is intended to establish interconnection with South Sulawesi system. The one of the transmission lines will be built 150 kV Raha-Baubau transmission line. One of the main potential impacts of the transmission line is electromagnetic field radiation. The value of electromagnetic field generating by transmission line can be conducted by calculation and simulation as studied in this research. This research was used shadow conductor approach method. The calculation and simulation results were showed that the largest electric field value occurring at two coordinates points (-7,2) and (7,2) with 0.366778 kV/m. The largest magnetic field was happening at coordinate (0,2) with 3.186838 A/m or 0.004 mT. Both electric and magnetic field radiation were still below the specified standard value, 5 kV/m for the electric field and 0.1 mT for the magnetic field.
