EMI/RFI Site Testing, Utility & LV Electrical Distribution Simulations & Impact Analysis, EMI/RFI Shielding Designs, Fabrications & Installation & Final Commissioning
The British Petroleum Naperville Campus, located in Naperville Illinois, accomodates for 1,400 employees and contractors within 178 acres of land dedicated to Laboratory and pilot scale research. Spread out between six main building complexes, this research facility focuses on chemicals, ploymers, fuels, catalysts, and improvement of refining processes. Vitatech was contacted by the BP Naperville Center to ascess the environmental conditions of a laboratory suite for a future FEI TEM within close proximity to a wall mounted electrical panel in the hallway and ceiling conduits within the future TEM room. Recorded wideband 12 Hz to 50 kHz data indicated levels of 170 nT (1.7 mG) peak-to-peak in the vertical Bz axis at the future column. VitaTech designed and installed a 102 sq. meter (1,110 sq. ft.) six-sided AC ELF magnetic shield that attenuated the three-axes levels to under 10 nT (0.1 mG) p-p (actually down to 5 nT(0.05 mG) p-p) providing more than -30 dB in shielding attenuation.
