| Application
Power frequency electromagnetic
fields from electrical distribution systems are virtually
everywhere. The closer to a source -be it a transformer,
a feeder run or switchgear, the higher the field intensity.
To prevent interference with sensitive
electronic equipment, monitors and computers, as well as
to satisfy possible health concerns, major magnetic field
'polluters' can be located in remote areas of
a building. However, this is not always possible or practical
and may bring additional costs and limit the useful space.
Solution
The installation of electrical equipment
designed with Low Electromagnetic Field Emissions.
Rex Power Magnetics has developed a complete
line of Low Emission power and distribution transformers
that have the external stray flux attenuated by 95% or higher
of the standard transformer field radiation.
Unshielded transformers 300KVA - 3000KVA
produce electromagnetic fields in the order of 100 - 500mg
(milligauss) in the immediate vicinity of the unit. Rex
specially designed shielded transformers can lower these
emissions by a factor of 10 or higher depending on the specifications.
This allows for the transformers to be installed
at practically any location in a building without any restrictions
due to intrusive magnetic fields.
Image 1 above shows the effects
of the electromagnetic fields outside of the enclosure of a typical
non-shielded transformer.
Image 2 above shows the
effects of the electromagnetic fields outside of the enclosure of
a shielded transformer. Due to shielding of the enclosure, most
of the field radiation can be contained within the transformer itself.
