Abstract
Method for generating low magnetic fields from a three-phase conductor arrangement. Four phase conductors are used, one phase being split into two phase conductors which are arranged one on each side of the phase conductors of the unsplit phases in a planar phase arrangement. The two outer phase conductors are interconnected, thereby forming a loop. Capacitive elements can be arranged in the loop, preferably in loop-forming cross connections.

A method for reducing magnetic fields generated by a three phase electric conductor arrangement, said arrangement comprising first, second and third conductors, each conductor having a different phase, the method comprising the steps of:
- splitting the first conductor into two conductors;
- connecting the two conductors in a loop;
- and
- positioning the second and third conductors between the two conductors.
A method for reducing magnetic fields generated by an underground three phase electric conductor arrangement, said arrangement comprising first, second and third conductors, said second conductor being disposed between said first and third conductor, each of the three conductors having a different phase, the method comprising the steps of:
- placing a fourth conductor next to the third conductor at a distance approximately equal to a mutual distance between the first, second and third conductors;
- and
- connecting the fourth conductor to the first conductor in a loop.
A three-phase electric conductor arrangement, comprising:
- a first conductor having a first phase, said first conductor being split into two conductors, and said two conductors being connected in a loop;
- a second conductor having a second phase, said second conductor being disposed between said two conductors;
- and
- a third conductor having a third phase, said third conductor being disposed between said two conductors.
A three-phase electric conductor arrangement, comprising:
- a first conductor having a first phase, said first conductor having first and second portions, said first portion of the first conductor comprising a first pair of conductors connected in a loop;
- a second conductor having a second phase, said second conductor having first and second portions, said second portion of the second conductor comprising a second pair of conductors connected in a loop, the first portion of the second conductor being disposed between the first pair of conductors, and the second portion of the first conductor being disposed between the second pair of conductors;
- and
- a third conductor having a third phase, said third conductor being disposed between the first and second pair of conductors.
