In Atlanta and Savannah, Georgia, ELEXANA tests and delivers assessments of workplace electromagnetic environments where an employee, contractor, visitor, or technical role involves an implanted medical device, wearable medical electronics, or other sensitive equipment.

ELEXANA can test the surrounding EMF/RF, magnetic-field, EMI, and power-quality conditions, and may also perform non-compliance functional interference testing to observe how a specific device or device type behaves near workplace electrical infrastructure, motors, transformers, wireless systems, industrial equipment, laboratory instruments, and other potential field sources. This work is intended to support employer safety review, facilities planning, engineering troubleshooting, and practical risk-reduction decisions

ELEXANA is an award-winning industry leader recognized globally as a top-tier provider of full Electromagnetic Interference (EMI) services.

  • EMI/EMC/EMF Forensic Investigations identify and solve the causes of malfunctioning equipment in industrial, scientific research, and medical centers.

  • EMC Pre-Compliance Consulting includes on-site or in-lab testing, EMI/RFI troubleshooting, EMC/EMI mitigation design, and EMI filter design for products in development.

  • New Construction Building Design EMI/EMC Consulting for IT & data centers, production studios, laboratories, airports, hospitals, medical centers, high-end residential, and community development projects.

  • EMF/EMI/EMC Surveys for Implanted Medical Devices, Electrical Power, and Telecom Installations; ISO-17025 and OSHA Certified. > We now have a dedicated electrical engineer, Phillip D., with thirty years of field experience, who worked for the company that makes our survey test equipment. He specializes in conducting this fieldwork for us and leads the ELEXANA Field Test Division.

  • Magnetic, RF Faraday, TEMPEST, and HEMP Shield Consulting, including shielding effectiveness testing, shielding design, and material effectiveness testing.

  • Ground System Consulting, including 4-Point Wenner Soil Resistivity Testing, Kelvin 3-Point Testing, energized ground testing, micro-ohmmeter bond testing, and grounding design.

  • Electrical Power Consulting, including Three-Phase 5-wire and Single-Phase 4-wire I-V analysis, transient testing, SNR, THD, I-V Trend datalogging, infrared tests, wire tracing, deep measure, voltage drop (%), and conducted emissions.

Why Be Concerned About EMI?

Electromagnetic interference (EMI) causes latency, malfunctions, and sluggish performance in fine electronics such as computers, medical devices and equipment, pacemakers, financial trading platforms, graphic software, and recording equipment.

With the exponential increase of wireless technologies in Atlanta, Georgia, EMI has become common vernacular. Line noise, harmonic transients, dirty electricity, RFI (radio frequency interference), and electromagnetic coupling are synonyms.

How Do You Know It’s EMI?

An easy way to tell if you have an EMI issue is to observe the presence of any:

  • Overheating of any metal enclosures. Are enclosures very hot to the touch? (Inductive Heating)

  • Motor failures from overheating. (Voltage Drop)

  • Fuses blowing for no apparent reason (Inductive Heating and Overload)

  • Static or interference on sound or voice communication (Harmonic Line Noise)

  • Electronic equipment shutting down for no apparent reason (Voltage Distortion)

  • The computer malfunctions or locks up. (Voltage Distortion)

  • Flickering fluorescent or LED lights (Transformer Saturation)

  • Blinking incandescent lights (Transformer Saturation)

What are the Additional Benefits Gained as a Result of Reducing EMI?

  • Reduced Electrical Consumption

  • Cooler Equipment

  • Longer Lifetime for Equipment

  • Lowered Utility Bill

  • EMF Reduction for a Safer and Healthier Environment

  • Surge Protection for Your Entire Facility

  • Improved Screen Quality

  • Improved Audio

  • Phase Correction, Which Improves Efficiency and Performance

  • Cleaner Power Resulting from Transient Harmonic Attenuation

How Does EMI Occur?

Metal, of course, is a conductor of electromagnetism. If you have a strong electromagnetic field near a metal wire with an electrical current and/or voltage, the nearby electromagnetic field will magnetically converge, couple, and ride along with the original current. Imagine a surfer hopping onto his surfboard to ride that perfect wave.

The interference that will occur on an electronic is relative to frequency, the V/m (Volts per meter), and the magnetic flux of the intruding EMF.

Here is an example of a sine wave from a PSU made jagged by RFI, radio frequency interference.
