What is EN 50768?

EN 50768, also known as the European Standard for Electromagnetic Compatibility (EMC) of decentralized power generation, is a technical specification that defines the permissible emissions and immunity levels for decentralized power generation systems. These systems include all types of energy sources such as photovoltaic (PV) systems, wind turbines, and fuel cells. EN 50768 provides guidelines to ensure that these power generation systems do not interfere with other electrical equipment or networks and can operate harmoniously in an electromagnetic environment.

Emission Levels

One key aspect of EN 50768 is the regulation of emissions from decentralized power generation systems. The standard sets limits on the amount of electromagnetic interference (EMI) that can be emitted by these systems. This includes both conducted and radiated emissions. Conducted emissions refer to interference that is conducted through power and signal cables, while radiated emissions are the electromagnetic waves emitted into the surrounding environment. By defining these emission levels, EN 50768 aims to minimize the potential disruption these systems may cause to other nearby electrical devices, communication networks, and radio services.

Immunity Levels

In addition to emission levels, EN 50768 also addresses the immunity requirements of decentralized power generation systems. Immunity refers to the ability of these systems to withstand external electromagnetic disturbances without experiencing performance degradation or malfunction. The standard specifies the levels of immunity that these systems should possess to ensure reliable operation even when exposed to electromagnetic fields generated by sources like high-voltage power lines or industrial equipment. By adhering to the immunity levels defined in EN 50768, power generation systems can safely continue supplying electricity even in the presence of potentially disruptive electromagnetic environments.

Importance and Compliance

The importance of EN 50768 cannot be understated, as it ensures the safe and efficient integration of decentralized power generation systems into existing electrical infrastructure. Compliance with this standard is crucial for manufacturers, installers, and operators of these systems to guarantee that they do not cause harmful interference or experience performance issues in the presence of electromagnetic disturbances. Furthermore, adhering to EN 50768 provides confidence to end users that the decentralized power generation systems they employ are reliable, durable, and will not compromise the functionality of other electrical equipment in their surroundings.
