EMI Mitigation Design Support
At each project milestone, Vitatech reviews project documents (i.e. conceptual and schematic design, design development, construction/tender documents, and commissioning and certification). This review includes analyzing building construction techniques, electrical and mechanical schematics, as well as civil and utility plans.
Careful, ongoing assessments
Lab data sheets and equipment tool lists are reviewed in tandem with manufacturer’s installation guides to identify EMI/RFI thresholds and design needs related to protecting equipment, personnel, and patients. This information is then presented in a series of diagrammatic graphics, finite modeling, simulated predictions, and narratives analyzing and documenting each design phase’s progress.
We assist our clients with build to design and performance based bid-ready documents.
Large and small ferromagnetic masses in motion produce quasi-static DC geomagnetic field perturbations in the sub-extremely low frequency (SELF), 0 – 3 Hz band. These perturbations radiate from the source, generating quasi-static DC (EMI) in sensitive scientific, medical, and research equipment. Vitatech and the University of Alberta in Edmonton, Canada, collaborated on measuring the quasi-static DC fields from a passenger elevator in steel and concrete buildings. These field levels depend on the size, mass, and speed of the moving ferromagnetic object. It’s important to assess the distance from elevators, loading docks, and roads during preliminary design stages.
