jännitekeskukketta

Jännitekeskus, often translated as a voltage center or transformer substation, is a critical component of an electrical power distribution system. Its primary function is to reduce the high voltage of electricity transmitted from power generation plants to lower, more usable voltages for consumers and industrial users. This voltage transformation is achieved through the use of transformers.

These substations are typically located in areas where electricity needs to be distributed. They receive power at very high voltages, often tens or hundreds of thousands of volts, through transmission lines. Inside the jännitekeskus, transformers step down this voltage in one or more stages. The electricity is then routed to lower voltage distribution lines that serve residential areas, commercial buildings, and factories.

Besides voltage transformation, jännitekeskukset also play a role in power system protection and control. They house switchgear, circuit breakers, and protective relays that monitor the electrical system for faults, such as short circuits or overloads. These devices can automatically disconnect sections of the network in case of a problem, preventing damage to equipment and ensuring the safety of personnel and the public. Monitoring and control equipment allows operators to manage the flow of electricity, balance loads, and maintain the stability of the power grid. The design and placement of jännitekeskukset are crucial for efficient and reliable electricity delivery.
