Keskijännitepuolella

Keskijännitepuolella refers to the medium voltage side of an electrical distribution system. In many electrical grids, power is generated at high voltages and then stepped down for distribution. This medium voltage range typically falls between 1 kilovolt (kV) and 36 kV. It serves as an intermediate stage between the high voltage transmission lines and the low voltage lines that supply end-users like homes and businesses.

Equipment found on the medium voltage side includes transformers, switchgear, circuit breakers, and protective relays. These components are designed to handle the higher electrical pressures compared to low voltage systems but are less robust and complex than their high voltage counterparts. The medium voltage network is crucial for efficiently delivering power over moderate distances within urban and suburban areas before it is further reduced to the standard low voltages of 230V or 400V for final consumption. Safety protocols and maintenance procedures are stringent for the medium voltage level due to the significant energy levels involved. Understanding the "keskijännitepuolella" is fundamental to comprehending the architecture and operation of modern power distribution networks.
