Keskijännitealueet

Keskijännitealueet, also known as medium voltage areas, refer to a segment of electrical power distribution networks operating at voltages typically between 1 kilovolt (kV) and 36 kV. This voltage range is crucial for efficiently transmitting electricity from higher voltage transmission lines to lower voltage distribution networks that serve end-users like homes and businesses. In Finland, where the term "keskijännitealueet" is commonly used, these networks are essential for supplying electricity to a wide range of consumers.

The infrastructure within these areas includes substations that step down high voltages from the transmission grid to medium voltages, and then further down to lower voltages. Medium voltage lines are often found overhead on poles or underground in cables. The design and maintenance of these networks are critical for ensuring a stable and reliable power supply.

Keskijännitealueet play a vital role in the overall power grid architecture. They bridge the gap between bulk power transmission and local distribution, allowing for economical and practical electricity delivery over moderate distances. The specific voltage levels used within the medium voltage range can vary depending on the utility, the geographical area, and the specific application. Understanding these areas is key to comprehending how electricity reaches consumers.
