sähköjakeluverkko

Sähköjakeluverkko is the Finnish term for an electricity distribution network. It is the part of the power system that delivers electricity from the transmission system to end-users. This network typically consists of medium-voltage and low-voltage lines, substations, and transformers. The primary function of the sähköjakeluverkko is to step down the high voltages used in transmission to lower, safer voltages suitable for residential, commercial, and industrial consumption.

The network is usually owned and operated by local or regional distribution system operators (DSOs). These DSOs are responsible for maintaining the infrastructure, ensuring reliable power supply, and managing the flow of electricity. They also handle the connection of new customers and the installation of metering equipment. The design of a sähköjakeluverkko can vary, with some being overhead lines supported by poles, while others are underground cables, which are more aesthetically pleasing and less susceptible to weather damage but are more expensive to install and repair.

Modern sähköjakeluverkko systems are increasingly incorporating smart grid technologies. These advancements allow for better monitoring, control, and automation of the network. Smart grids enable features like remote meter reading, real-time fault detection, and the integration of renewable energy sources such as solar and wind power. This enhances efficiency, reliability, and the ability to manage demand-side responses, ultimately contributing to a more resilient and sustainable energy system for consumers.
