2. 15 kV AC railway electrification - Wikipedia

   en.wikipedia.org/wiki/15_kV_AC_railway...

   Separate plants supply railway power in Austria, Switzerland and Germany, except for Mecklenburg-Western Pomerania and Saxony-Anhalt; converters powered by the grid supply railway power in those two German states plus Sweden and Norway. Norway also has two hydro-electric power plants dedicated for railway power with 16 + 2 ⁄ 3 hertz output.

3. List of railway electrification systems - Wikipedia

   en.wikipedia.org/wiki/List_of_railway...

   This is a list of the power supply systems that are, or have been, used for railway electrification. Note that the voltages are nominal and vary depending on load and distance from the substation. As of 2023 [update] many trams and trains use on-board solid-state electronics to convert these supplies to run three-phase AC traction motors.

4. Mains electricity by country - Wikipedia

   Mains electricity by country includes a list of countries and territories, with the plugs, voltages and frequencies they commonly use for providing electrical power to low voltage appliances, equipment, and lighting typically found in homes and offices. (For industrial machinery, see industrial and multiphase power plugs and sockets.) Some ...

5. Voltage converter - Wikipedia

   en.wikipedia.org/wiki/Voltage_converter

   A simple voltage dropper can be used to reduce the voltage for low-power devices; if more than 12V is required, or for high-powered devices, a switched-mode power supply is used. The output will usually be DC in the range 1.5–24 V. Power supplies that output either 100–120 V AC or 210–240 V AC are available; they are called inverters ...
