Electromagnetic compatibility (EMC) - Part 2-12: Environment - Compatibility levels for low-frequency conducted disturbances and signalling in public medium-voltage power supply systems

This document outlines compatibility levels for low-frequency disturbances and signal transmission specifically within medium voltage public power supply networks. It addresses the electromagnetic environment applicable to power distribution systems, providing a framework for assessing how electrical equipment interacts with the surrounding electromagnetic field. The content focuses on defining the characteristic environment where such disturbances are expected to occur, ensuring consistency across different regions and applications. By establishing these levels, the document supports the design and deployment of devices that can operate reliably within the specified power infrastructure. It details the parameters associated with voltage dips, short interruptions, and other low-frequency phenomena common in medium voltage settings. The scope covers the interaction between the power network and connected equipment, aiming to harmonize performance expectations. This technical guidance facilitates interoperability and reduces the risk of malfunction due to electromagnetic interference in critical distribution zones.
