Sähköjakokeskukset

Sähköjakokeskukset, often translated as electrical distribution centers or substations, are crucial components of a power grid responsible for modifying and distributing electricity. They serve as intermediate points between high-voltage transmission lines and lower-voltage distribution networks that supply power to homes and businesses.

The primary function of a sähköjakokeskus is to reduce the voltage of electricity. This is achieved through the use of transformers. Electricity is transmitted over long distances at very high voltages to minimize energy loss. However, these high voltages are unsafe and unsuitable for direct use by consumers. Within the sähköjakokeskus, transformers step down the voltage to levels that are appropriate for local distribution networks, typically in the range of tens of kilovolts.

Beyond voltage transformation, sähköjakokeskukset also house switching equipment. Circuit breakers and disconnect switches allow operators to control the flow of electricity, isolate parts of the network for maintenance, or reroute power in case of faults or outages. This ensures the reliability and safety of the power supply. Monitoring and control systems are integrated to track the performance of the equipment and manage the distribution of power efficiently. These centers are vital for maintaining the stability and functionality of the entire electrical infrastructure.
