MVjärjestelmien

MVjärjestelmien is a Finnish term that translates to "MV systems" or "medium voltage systems." In electrical engineering, medium voltage typically refers to electrical potential levels ranging from 1 kilovolt (kV) up to 36 kV. MV systems are a crucial part of the electricity distribution network, bridging the gap between high voltage transmission lines and low voltage distribution to end-users.

These systems are used to carry electricity from substations to various points within a community or industrial area. They are often found in urban areas, industrial parks, and large commercial facilities. MV systems utilize overhead power lines or underground cables to transmit power. The voltage is stepped down from higher transmission voltages at substations using transformers, and then further reduced to low voltage (typically 230/400V in Europe) at local distribution points closer to consumers.

Components of an MV system include switchgear, transformers, circuit breakers, insulators, and protective relays. These components are designed to handle the higher power flow and voltage levels found in the medium voltage range. The design and maintenance of MV systems are critical for ensuring reliable and safe electricity supply. They play a vital role in powering homes, businesses, and industries, and are an essential element of modern electrical infrastructure.
