Impact of the phase positions on the electric and magnetic field of high-voltage overhead lines

The magnetic and the electric field of a three phase double circuit high-voltage overhead power line depend on the geometrical arrangement of the conductors and on the allocation of the phases. This paper shows the resulting magnetic and electric fields for three different conductor arrangements (i.e. given tower geometries) often found in Europe - for all possible phase allocations respectively. In addition, a method is derived to identify exemplarily the best phase allocation for specific immission of a 3-level-tower, as well as an evaluation method of the highest field value without knowing the actual phase allocation.
