Keskijännitetasoilla

Keskijännitetasoilla refers to the medium voltage level in electrical power distribution systems. This voltage range typically falls between low voltage (typically below 1000 volts) and high voltage (typically above 50,000 volts). In many countries, the medium voltage range is defined as being between 1 kilovolt (kV) and 36 kV or 52 kV, though specific definitions can vary by region and utility.

Medium voltage is used to transmit electricity from substations, where the voltage has been stepped down from transmission levels, to local distribution points like commercial buildings, industrial facilities, and smaller residential areas. It offers a balance between efficient transmission over moderate distances and the ability to be further stepped down to safe low voltage levels for end-user consumption without requiring extremely large and expensive infrastructure.

Equipment operating at medium voltage includes transformers, switchgear, cables, and overhead power lines. These components are designed to safely handle the higher electrical pressures compared to low voltage systems. The design and maintenance of medium voltage networks are critical for reliable power supply and public safety. Regular inspections and adherence to safety protocols are paramount when working with or near medium voltage equipment. The transition from medium voltage to low voltage is typically achieved through distribution transformers located at or near the point of consumption.
