DCjärjestelmät
DCjärjestelmät, often referred to as DC systems, are electrical systems that operate using direct current. Unlike alternating current (AC) systems where the direction of current flow reverses periodically, in DC systems, the electric charge flows in only one direction. This fundamental difference influences their design, application, and components.
Historically, DC systems were the first electricity distribution method, pioneered by Thomas Edison. Early electrical grids
Despite the dominance of AC in public grids, DC systems remain crucial in numerous specialized applications.
Furthermore, high-voltage direct current (HVDC) transmission is used for transmitting large amounts of power over very
