The configuration of the magnetic field of a
transmission line as well as the amplitudes and the
vectors of the field are generally well known today
1, 2. The magnetic field can interfere electrically
with sensitive electric circuits in control,
measuring and communication equipment. In such
cases it can be necessary to reduce the magnetic
field at or around the location of interference.
The paper describes the various methods which can
practically be applied to reduce the magnetic
field, ranging from shielding methods to varying
the conductor arrangement on the tower or
compensating the field by a counter field. Some of
the methods were tested near a real line. It is
shown that in a limited space and with a
reasonable effort it is possible to reduce the
magnetic field of transmission lines to amplitudes
which cause no critical interference. Out of the
various methods investigated, classified and
assessed in the paper the shielding by sheet copper
or steel appears to be most effective with the
advantage of low running cost.
