Sekundärnätet

Sekundärnätet, often translated as "secondary network" or "secondary grid," refers to the lower voltage distribution lines that carry electricity from substations to individual homes and businesses. This is in contrast to the primary grid, which comprises high-voltage transmission lines that carry power over long distances. The process of transforming high-voltage electricity to a usable voltage for local distribution occurs at substations, where transformers step down the voltage significantly. From these substations, the secondary network branches out, typically using medium-voltage lines that are further reduced to low-voltage lines closer to the end-users. These low-voltage lines then connect directly to buildings via service drops. The design and maintenance of the secondary network are crucial for ensuring reliable and safe electricity supply to consumers. Factors like load balancing, fault detection, and protection systems are integral to its operation. Urban areas generally have more complex secondary networks due to higher population density and greater demand, often utilizing underground cabling for aesthetic and protective reasons, while rural areas may rely more on overhead lines.
