3. Low-voltage networks
3.1 Different types of energy networks
In connection with the issue of overvoltage control, low-voltage power networks can behave quite differently depending on how potentials are fixed in relation to metallic grounds and earth.
These are known as earth connection diagrams (figure 11 ), or neutral systems.

Standards and norms
- Low-voltage arresters – Part 11: Surge arresters connected to low-voltage systems – Requirements and test methods. - NF EN 61643-11 - 05-2014
This standard covers arresters for low-voltage AC networks. Specific versions for DC applications are under development (IEC 61643-31 for arresters for photovoltaic applications and IEC 61643-41 for other DC applications. In Europe, there is already a standard for...
