The authors propose a full three-dimensional (3D) calculation model based on a
multipole technique able to predict the magnetic field pollution outside of indoor
medium voltage/low voltage (MV/LV) transformer substations.
demonstrate that the proposed model may be advantageously used in all
problems related to the characterization of the electromagnetic environment
around a MV/LV transformer substation.
They also show how the model may be
used to support the optimised design of the cabin layout when this solution is
sufficient to assure the reduction (below the exposure limits fixed by law) of the
magnetic flux density in target volumes within civil buildings.
In particular, the
proposed algorithm has been applied to evaluate the magnetic flux density levels
in the neighbourhood of a typical indoor MV/LV cabin placed at ground zero of
a civil building (and therefore bordering on houses and/or offices).
In addition, in
order to mitigate the magnetic field outside the transformer substation, using the
proposed calculation code an attempt was made to design the layout of the cabin
by rearranging the position of the LV distribution switchboard (i.e., the power
magnetic pollution, magnetic field calculation, magnetic mitigation,
MV/LV transformer substation, distribution power systems.
The installation of a new indoor MV/LV transformer substation (see fig.
urban areas may be a very hard task with respect to the problems related to
human exposure to power frequency magnetic fields.
In fact, these cabins are
often placed in civil buildings therefore they border on houses or offices (i.e.,
places where people live for a large part of the day).
