Abstract :
To improve understanding of 60 Hz magnetic field characteristics in AC power substations, a numerical calculation of a 60 Hz magnetic field in the 187 kV switchyard of a 187/66 kV substation in service is conducted by using a simple analytical method. The magnetic field profiles near ground level are calculated for various current conditions, and described in terms of the contour maps of magnetic flux density. Effects of the line and bus current conditions, the bus phasing arrangement, and the line and bus geometrical configuration on the substation magnetic field profiles are also investigated
