jakelujohdoissa
Jakelujohdoissa refers to the network of electricity distribution lines and equipment that delivers electric power from substations to customers within a region. In the Finnish energy system it covers the lower part of the electrical grid, typically operating at low to medium voltages suitable for local and feeder distribution. The network includes conductors (overhead lines and underground cables), insulators, poles or trenches, transformers, switchgear, protection devices, and associated control and communication systems that together ensure safe and reliable delivery of electricity to homes, businesses, and public services.
Distribution networks comprise both overhead and underground elements, chosen based on terrain, cost, and reliability considerations.
Regulation, operation, and reliability
Distribution system operators (DSOs) oversee the daily operation and maintenance of these networks, while national authorities
Recent developments focus on modernization through smart grid technologies, remote sensing, and automation, enabling better integration
