Electromagnetic compatibility (EMC) testing of stationary installations.

Electromagnetic compatibility (EMC) testing is a set of standardized procedures required to verify that electronic equipment complies with electromagnetic compatibility requirements. The depth and complexity of EMC tests vary depending on the type of equipment and its area of application.

The tests are crucial to ensure that the device complies with established international standards.

If emissions exceed the permissible limits, manufacturers are required to review the design of their products and implement additional measures to reduce emissions, such as shielding or filters.

Immunity tests assess a device's resistance to external interference. During these tests, the device is deliberately exposed to varying levels of electromagnetic interference and its behaviour under these conditions is evaluated. Tests may include exposure to electrostatic discharges, fast transients, voltage fluctuations, and high-intensity electromagnetic fields. Successful completion of these tests indicates that the equipment can function normally even in the presence of significant external influences.

In real-world operating conditions, there are many different types of radiation. The ability of technical devices to operate stably in the presence of electromagnetic interference, without causing unacceptable interference to other products, is what electromagnetic compatibility is all about.

Manufacturers of stationary equipment must take into account the technological evolution of their systems, as well as various electronic equipment located nearby.

EMC testing is carried out in a laboratory, and in some cases, testing is carried out ‘on site’. To obtain reliable information, tests can be carried out at the manufacturer's premises.

Not every laboratory is capable of testing stationary installations. Testing stationary equipment on site requires the expertise of specialists and specific testing equipment.
