VitaTech Engineering performed an AC ELF EMF Study
and Shielding Assessment of an internet warehouse facility under construction
in Georgia and was contracted in install, test and certify an AC extremely
low frequency (ELF) magnetic shield.
An assessment of the overall floor designs, electrical
service placement and configuration, and the average and seasonal peak
load electrical conditions was performed. This information was used
to design a magnetic shield for this facility.
In September 2000, A 18,600 sq.ft. magnetic shield
was installed along the interior walls of the PDU Substation Train,
the two Electrical/Distribution Rooms and the two Chiller Plant Rooms.
The shield complied with a 10mG magnetic flux density performance requirement
measured 1-meter from the shielded walls in over 95% of the shielded
area.
