  2. Utility frequency - Wikipedia

    en.wikipedia.org/wiki/Utility_frequency

    The waveform of 230 V and 50 Hz compared with 120 V and 60 Hz. The utility frequency, (power) line frequency (American English) or mains frequency (British English) is the nominal frequency of the oscillations of alternating current (AC) in a wide area synchronous grid transmitted from a power station to the end-user.

  3. Mains electricity by country - Wikipedia

    en.wikipedia.org/wiki/Mains_electricity_by_country

    Voltages in this article are the nominal single-phase supply voltages, or split-phase supply voltages. Three-phase and industrial loads may have other voltages. All voltages are root mean square (RMS) voltage; the peak AC voltage is greater by a factor of 2 {\displaystyle {\sqrt {2}}} , and the peak-to-peak voltage greater by a factor of 2 2 ...

  4. Electric power distribution - Wikipedia

    en.wikipedia.org/wiki/Electric_power_distribution

    Most of the Americas use 60 Hz AC, the 120/240 volt split-phase system domestically and three phase for larger installations. North American transformers usually power homes at 240 volts, similar to Europe's 230 volts. It is the split-phase that allows use of 120 volts in the home. Japan's utility frequencies are 50 Hz and 60 Hz.

  5. Electricity sector in Japan - Wikipedia

    en.wikipedia.org/wiki/Electricity_sector_in_Japan

    The electric power industry in Japan covers the generation, transmission, distribution, and sale of electric energy in Japan. Japan consumed approximately 918 terawatt-hours (TWh) of electricity in 2014. [1] Before the 2011 Fukushima Daiichi nuclear disaster, about a quarter of electricity in the country was generated by nuclear power. In the ...

  6. Mains hum - Wikipedia

    en.wikipedia.org/wiki/Mains_hum

    Mains hum, electric hum, cycle hum, or power line hum is a sound associated with alternating current which is twice the frequency of the mains electricity.The fundamental frequency of this sound is usually double that of fundamental 50/60 Hz, i.e., 100/120 Hz, depending on the local power-line frequency.

  8. Power inverter - Wikipedia

    en.wikipedia.org/wiki/Power_inverter

    Utility frequency conversion - if a user in (say) a 50 Hz country needs a 60 Hz supply to power equipment that is frequency-specific, such as a small motor or some electronics, it is possible to convert the frequency by running an inverter with a 60 Hz output from a DC source such as a 12V power supply running from the 50 Hz mains.
