välijaotusjaam

A välijaotusjaam, often translated as an intermediate distribution station or substation, is a crucial component in electrical power transmission and distribution systems. Its primary function is to step down the high voltage from transmission lines to lower voltages suitable for distribution to end-users or to other, smaller substations. These stations act as intermediate points in the network, facilitating the efficient and safe delivery of electricity.

Välijaotusjaamad are typically located between the main power generation plants and the final delivery points, such as residential neighborhoods or industrial complexes. They house a variety of electrical equipment, including transformers for voltage conversion, circuit breakers for protection and switching, and busbars to connect different circuits. The design and capacity of a välijaotusjaam are determined by the power demand of the area it serves and the voltage levels involved.

These substations play a vital role in managing the flow of electricity, allowing for flexibility in the power grid. They enable the isolation of faults, rerouting of power in case of outages, and maintenance without disrupting the entire system. The strategic placement of välijaotusjaamad is essential for maintaining grid stability and ensuring a reliable power supply to consumers. They are a key element in the complex infrastructure that underpins modern electrical grids.
