Transmissionsnetværkene

Transmissionsnetværkene, often translated as transmission networks, refers to the infrastructure and systems used for conveying electricity over long distances. These networks are a crucial part of any modern power grid, acting as the high-voltage backbone that connects electricity generation sources to distribution substations closer to consumers.

The primary components of transmission networks include high-voltage power lines, typically supported by large pylons, and substations. These substations are equipped with transformers that step up the voltage from generators to very high levels (e.g., 132 kV, 220 kV, 400 kV) for efficient long-distance transmission. This high voltage minimizes energy loss due to resistance in the conductors. At the receiving end, other substations step down the voltage to lower levels suitable for distribution networks.

The development and maintenance of robust transmission networks are essential for grid stability, reliability, and the integration of renewable energy sources, which are often located far from demand centers. Managing these networks involves complex monitoring, control, and protection systems to ensure a constant and secure flow of electricity. International interconnections between national transmission networks also play a significant role in enhancing energy security and facilitating energy trading.
