rapid spread of new technology has raised the level
of concern about electric and magnetic field (EMF)
interference and has greatly increased the consequences
of that interference. Substantial research, funded
by the electric utility industry and others, has improved
the characterization and management of extremely low
frequency (ELF) magnetic fields from power systems,
particularly from sources inside buildings, like transformer
vaults, switch gear and bus ducts. Increasing sensitivity
of computer monitors, medical devices and other electronic
equipment to ELF magnetic fields requires field management
and suppression technology that achieves substantially
lower values than available through conventional techniques.
Most recently, real estate and architectural
professionals have demanded preemptive design of low
EMF buildings - creating buildings that are intrinsically
immune to electromagnetic interference from internal
and external sources.
CEI carries out site
investigations and is accredited for on site EMC testing.
We also provide the measurement of shielding effectiveness
from DC to the microwave frequency range.
