VitaTech engineers and technicians perform Magnetic Flux Density EMF anf RF Simulation Modeling of EMI sources (using our state-of-the-art software) in proposed buildings that compromise research, imaging and laboratory equipment. These EMI/RFI sources include EMI interference from the electrical infrastructure and RFI sources:
- Exterior substation
- Primary feeders entering the building
- Busway/conduit risers
- Basement level main electrical room ( main switchgear in the main electrical room)
- Emergency generators and automatic transfer switches (ATS)
- UPS systems
- Large electric motors (HVAC fans, pumps, etc.)
- Variable speed controllers
- TV/AM/FM Broadcast transmitters
- WiFi Nodes
- Cellular Phones
- Cell Towers
- Variable Frequency Drive (VFD) Pumps and motors
- RFID scanners
- Fluorescent Light Ballasts
- Owner recommended electromechanical and radio frequency devices
Predicted emission profiles are generated for the main transformers and any large distribution transformer (45 kVA and greater) under 65% load conditions located in electrical rooms adjacent to EMI sensitive areas.
Electrical infrastructure and radio frequency source examination of the proposed building drawings is performed and all predicted and simulated magnetic flux density emission data is applied to ascertain the potential effects on research and laboratory equipment from:
1) Radiated and induced AC ELF and DC magnetic fields;
2) Stray electrical currents (traction currents from the trains);
3) Transient electrical conditions, including impulses; and,
4) Any other conditions associated with electrical and radio frequency aspects of the installation pertinent to scientific research instruments.
EMF and RF Modeling and Simulations are summarized showing potential EMI/RFI problems in laboratories, offices, telephone/ network and server/routing closets, audio/video and data cable paths and in telecommunications and computer rooms. Survey data plots and simulations will be presented in color 2-D contour plots overlaid on the floor plans and 3-D graphics. Identified EMI problems based upon the simulations will be discussed and corrective solutions (i.e., moving EMI sources, shielding, etc.) with estimated costs to mitigate recommended.
