Wechselnetz
Wechselnetz refers to a type of electrical grid infrastructure designed to transmit alternating current (AC) electricity over long distances. Unlike direct current (DC) systems, which are more efficient for high-voltage, long-distance transmission, AC systems are widely used due to their ability to be easily transformed to different voltage levels using transformers. This adaptability makes AC ideal for both high-voltage transmission and local distribution to end-users.
The term *Wechselnetz* is primarily used in German-speaking regions, where it contrasts with *Gleichstromnetz* (DC grid).
In Germany, the national grid is predominantly an AC system, operated by transmission system operators such
The advantages of an AC grid include lower costs for transformers and the ability to synchronize multiple
