Beschreibung:

The longer the power transmission path is for alternating current, the higher the voltage must be in order to minimize the transmission losses. Therefore, with a central electric power supply, the electric power at the power plants is stepped up from approximately 30 kV to, for example, 380 kV for long-distance transmission. It is then stepped down for regional distribution, for example, to 60 kV or 30 kV, and for local distribution to households to 230 V.
