What We Do - AC & DC EMI Modeling Services
At VEC, we specialize in high-resolution magnetic field modeling and simulation to help you identify, predict, and mitigate electromagnetic interference (EMI) issues. Our EMI consulting services support your project from early-stage planning through post-installation validation, helping you build environments that support sensitive equipment and meet project specs.
Whether you're in the design development phase or refining a completed plan, our EMI Modeling approach provides the confidence you need to move forward.
AC EMI Modeling
We utilize 3D finite element analysis, with a resolution of up to 0.1 m, and cross-check them against field-validated data and in-house testing to provide a model of the AC electromagnetic fields within the facility. These models allow us to:
• Visualize interference from electrical sources
• Provide recommendations regarding electrical equipment placement and conduit routing
• Evaluate the effectiveness of shielding (EMT, RMC, etc.)
• Compare shielded vs. unshielded scenarios
• Recommend mitigation strategies tailored to your site and equipment
Note: Each model is computationally intensive and can take up to 48 hours to run. That’s why we stay in close communication throughout the process to ensure accuracy and adaptability.
DC EMI Modeling
VEC has compiled a proprietary database of elevator-related DC magnetic field data, enabling us to simulate DC EMI fields from both freight and passenger elevators. Our team creates DC EMI maps to visualize field strengths and assess their impact on planned equipment locations, helping to ensure that sensitive tools operate without disruption.
What a typical project looks like
Industrial projects often depend on many significant sources of mechanical acoustic noise to support power generation and other critical infrastructure functions. VEC can help ensure you comply with local codes and ordinances during your project.
What a typical project looks like
We know that every buildout is unique. Our approach to magnetic field design is tailored to your specific equipment, environment, and goals. Here’s what a typical VEC EMI project includes:
1. Review site drawings & instrument/equipment list
2. Perform baseline AC/DC field testing
3. Collaborate with your electrical engineering team to build a 3D model based on planned electrical loads
4. Integrate VEC recommendations into the electrical design
5. Evaluate the cost-benefit of mitigation strategies such as passive shielding or active magnetic field cancellation
6. Provide detailed construction drawings or coordinate with shielding vendors
7. Conduct post-installation site testing to confirm field levels meet equipment requirements
We provide turnkey EMI consulting services that ensure compliance, performance, and peace of mind—before and after installation.
What We Need From You
To build a reliable and accurate EMI model, we ask for the following:
• Electrical blueprints per floor
• Wire types, sizes, amperage, and shielding
• Planned conduit routing
• Distribution panels and transformer specs/locations
• Passive shielding locations
• Building dimensions, especially floor heights and tool locations
• On-site testing is helpful to quantify ambient magnetic field levels
• (Optional but helpful): Locations and specs for any tools or instruments being installed
💡 Good news: We don’t require lighting panel details, as they produce negligible EMI.
What You Get From VEC
At the conclusion of your project, you'll receive a comprehensive EMI modeling report designed to support clear decision-making and project documentation. Reports include:
• Executive Summary & Recommendations
• Modeling Assumptions + Potential Sources of Deviation
• Modeled EMI Field Results for discussed Scenarios
• Tool Specifications & Required Mitigation Plans
• Side-by-side model visuals for informed decision-making
Our reports are trusted by engineers, architects, and key stakeholders across industries to validate EMI design decisions and avoid costly redesigns.
