A Comparative Study of Magnetic Fields in 115 kV Single Circuit Transmission Line of Thailand

This paper presents the analysis of magnetic field effects on 115 kV single circuit transmission line at the ground and around conductors by considering two study cases i) single circuit with single conductor ii) single circuit with bundled conductor. The magnetic field simulation concerned only 24-hour load currents supplying during weekends. This paper focused on a comparative study between two study cases and compared the results obtained during. The simulation results showed that the value of magnetic fields at the ground and around conductors of single circuit with single conductor case were less than those of the bundled conductor.
