mellemhøjspændingsnettet

Mellemhøjspændingsnettet, often abbreviated as MHV-nettet, is a crucial part of the electricity distribution system in Denmark. It serves as an intermediary link between the high-voltage transmission network and the low-voltage network that delivers electricity to homes and businesses. The voltages on this network typically range from 10 kilovolts (kV) to around 50 kV, varying by region and specific function.

The primary role of the MHV-nettet is to efficiently transport electricity over medium distances from substations that step down power from the high-voltage grid. It is designed to carry larger amounts of power than the low-voltage network but with lower losses than the high-voltage transmission lines. This network is characterized by overhead lines supported by poles and underground cables, forming an extensive web across urban and rural areas.

Key components of the MHV-nettet include transformers, which are essential for stepping voltage up or down at various points, and switchgear, used to control and protect the network from faults. Substations play a vital role, connecting the MHV-nettet to both the higher voltage transmission grid and the lower voltage distribution grid. The reliability and stability of the MHV-nettet are paramount to ensuring a consistent and safe supply of electricity to end-users. Regular maintenance and upgrades are undertaken by grid operators to maintain its integrity and adapt to evolving energy demands, including the integration of renewable energy sources.
