Compliance to EMC standards is a must for every company that manufactures various electrical products. Know more about EMC consulting & it's great benefits.

1. An Introduction to EMC
Consulting & Its Huge Benefits
Almost all electronic and electrical equipment is prone to creating what is known
as “interference” in one way or another. One of the most common examples
would be radio interference. This usually occurs from motorcycle engines that are
poorly suppressed or electric drills. This type of interference causes frustration and
irritation to those listening to the TV or radio. On a more serious level, this
interference can also affect aircraft navigation systems or emergency radio
communication.

2. Other kinds of interferences can be caused in the power supply circuits in just
about any lighting system or electronic product. These types of circuits are known
for “distorting” the voltage of the main supply. This results in the drawing of what
is known as “harmonic currents" from the mains. These “harmonics” are displayed
at frequencies that can eventually lead to a failure in an electrical distribution
network.
These interferences relate to what is known as “emissions”. This will sum up to
levels of “electrical” noise in an environment. Certain environments like industrial
areas are much worse than the others. Other environments such as residential
homes are quieter. The energy in the radiated emissions is mainly composed of the
magnetic field or voltage stress. These are various forms of what is known as
electromagnetic emissions.

3. These emissions’ should be handled by ensuring that any product can still operate
in a satisfactory manner where it will be utilised. This is known as a measure of its
immunity or susceptibility to electromagnetic noises. There are various aspects
involved in this measure. These can include:
 Conducted and radiated RF requirements;
 Magnetic fields;
 ESD;
 Brownouts;
 Dropouts; and
 Mains power glitches
The main goal of FCC rules and the EU directive is to make sure every emission is
kept low as well as presenting high immunity levels. This principle is known as EMC
(Electromagnetic Compatibility). Products declared compatible in regards to this
principle are known as EMC Compliant.

4. Every company that manufactures and releases electrical products has to make
sure that the product is compliant in a consistent manner. One of the only
methods would be to test the “immunity” and measure the “emissions.” For
products produced on the lower scale, only one or two products need to be tested.
For products produced on a higher scale, samples will need to be tested more
regularly.
The compliance strategy can be used in test labs in order to test out specific
products. The optimal route will all depend on the amount of products and the
volume that will require testing. In general, if over five testing is required within an
annum, self-testing can offer advantages in regards to timescale, cost and
convenience.

5. There are many clear benefits when it comes to testing products through a
development cycle. Associated delays and costly redesigns can be avoided. It is
always advisable to begin testing the compliance of a new product in the early
stages. A test that fails towards the end of a development cycle of a product is
proven to be highly expensive and a great loss of time.
