Minimizing Power Frequency Magnetic Fields During a Commercial Building Power Upgrade

摘要

In this case study, the management of a commercial office building in Los Angles, California planned to substantially increase capacity of its power facilities, both to support increasing demands from tenants' new technology equipment and to provide for future growth. Space and access restrictions in the basement forced a decision to locate a new utility transformer and distribution equipment in an existing street level retail space, with tenant spaces on all sides and above. Computer models confirmed that elevated power frequency magnetic field levels were likely to exist in the adjacent tenant spaces after installation of the new utility transformer facility. Tenants adjacent to the new electrical facilities space expressed concern about equipment interference and potential health problems.
