Why Be Concerned About EMI?

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

With the exponential increase of wireless technologies in Cincinnati, Ohio, 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)
Computer malfunction or locking 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.

The analogy of wind and water wonderfully illustrates the concept of EMI.

If there is a slow and easy breeze moving across the surface of a lake, you will see ripples or small mercurial waves in the water.

When wind velocity and force increase, you will see more turbulent water. This resembles EMI.

The concern for EMI is the reason your airline pilot calmly orders you to place your phone on “airplane mode.” Accumulative electromagnetism from the many cell phones reflecting off of hard surfaces inside the cabin could intrude onto the computer’s circuitry that controls the landing gear.

EMI is why certain hospital wings will have cell phone-restricted areas.

If you think that your fine electronics may be affected by EMI, then you are on your way to having your problem solved. We’re here for you from Monday through Friday.

What is EMF Testing?

An EMF Testing, called an EMF Measurement Survey, is a non-invasive assessment of the electromagnetic fields within a residential or commercial property. It involves a systematic method of measuring and recording non-ionic radiation emanating from the Earth and various human-made technologies. Measurements are monitored and recorded during a relatively brief or data-logged over a longer designated period.

An EMF survey includes a full assessment of the frequency bandwidth, size, shape, strength (measured as power density in watts per square meter, voltage per cubic meter, or flux density in nanoTeslas or milliGauss), behavior (is the field moving or is it relatively stationary), quality (are there other fields coupled onto the targeted, measured field and what are their characteristics), and the identification of the source-point(s) of each particular EMF field.

An EMF survey is an assessment of the defining characteristics of each electromagnetic field on a property and should include the following:

Frequency bandwidth within the electromagnetic spectrum. This helps determine attributable effects, aspects, and applications.
Size dimensions.
Shape. Rarely is an EMF field in the shape of a box.
Strength; is determined by the relative power density divided by the distance from the source point. The strength of a field is measured, in a unit appropriate to the particular field, in either watt per square meter, voltage per cubic meter, or flux density in nanoTeslas or milliGauss
action; determination of the field’s movement or lack thereof.
Quality; is the field unadulterated or coupled with other electromagnetic fields from the same or different source points. (Assess each of the coupling fields.)
Identification of the source point (s) of each particular EMF field.

What is the Purpose of an EMF Measurement Survey?

Assess a property to develop solutions for the health and safety of its occupants.
Assess the environment for remediating electromagnetic interference causing electronic malfunction.
Assess property to design shielding or other mitigation solutions.
Assess a building or new construction for the potential of geopathic structural damage.
Help educate the client and answer all EMF-related questions in layman’s terminology.

What is an EMF Consultation?

An EMF Consultation is either:

an on-site service that includes an EMF Measurement Survey at your residence or business, identification and documentation of all electromagnetic radiation issues which could affect any occupants’ health, identifying the source points with instructions on how to fix these issues, and if possible: fixing the issues at the time of identification (with the client’s permission.) If a licensed electrician, power company service technician, plumber, or cable provider is required, then we provide instructions on how they can fix these problems in a separate report. Yes, this is in our unique training and why you only want an EMRS. This consultation service could include an extended remediation discount sheet and a phone consultation follow-up.
a Phone Service (Telephone, FaceTime, Skype, Zoom) includes listening to all the client’s concerns, providing clear and concise education, asking troubleshooting questions, and proposing remediation solutions. These sessions may include photos, emails, Zoom drawing shares, live videos, links, etc. This service could include an extended remediation discount sheet and a phone consultation follow-up.
