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.
English: Map of the National Grid in Great Britain, featuring all transmission lines and substations at 220 kV and above. Derived from OpenStreetMap data in February 2023, which is, as far as I am aware, an accurate representation of the current grid.
The British grid is not synchronized with the Continental Europe frequency, but it is interconnected using high-voltage direct current (HVDC) via the HVDC Cross-Channel (IFA), BritNed, Nemo Link, IFA-2, North Sea Link, Viking Link and ElecLink links. In 2014, before Nemo Link, IFA-2, ElecLink and North Sea Link became operational, the United ...
