Virranjakelussa

Virranjakelussa, often translated as "power distribution" or "electricity distribution," refers to the segment of the electricity supply network that delivers electricity from the high-voltage transmission system to end-users. This process begins after the electricity has been generated and transported across long distances via high-voltage transmission lines. The voltage is then progressively reduced at substations before reaching the local distribution network.

The distribution network typically consists of medium-voltage lines, often seen on utility poles or underground cables, which carry electricity to neighborhoods and industrial areas. Within these areas, further voltage reduction occurs through local transformers, usually mounted on poles or situated in ground-level boxes, to bring the voltage down to the levels required by residential, commercial, and industrial consumers.

The primary function of virranjakelussa is to ensure a reliable and safe supply of electricity to all connected customers. This involves managing the flow of power, maintaining the integrity of the distribution lines, and responding to faults or outages. Distribution companies are responsible for the operation, maintenance, and expansion of this network. Efficient virranjakelussa is crucial for modern society, enabling everything from household appliances to complex industrial processes. Challenges in this area include managing network load, integrating renewable energy sources, and minimizing energy losses during transmission.
