Keskijännitejärjestelmät
Keskijännitejärjestelmät, known in English as medium voltage systems, refer to electrical power distribution networks that operate at voltages typically between 1 kilovolt (kV) and 36 kV. These systems are crucial for transmitting electricity from substations, where high voltage is stepped down, to industrial facilities, commercial buildings, and residential areas where the voltage is further reduced to lower levels for end-use. They bridge the gap between high voltage transmission lines and low voltage distribution networks.
The primary purpose of medium voltage systems is to efficiently transport electricity over moderate distances. Using
Components of a medium voltage system include transformers for voltage transformation, circuit breakers and switches for
