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.
India's grid is connected as a wide area synchronous grid nominally running at 50 Hz. The permissible range of the frequency band is 49.5-50.5 Hz, effective 17 September 2012. The Union Government regulates grid frequency by requiring States to pay more when they draw power at low frequencies. [3]

A 50 Hz ±5 Hz vibrating-reed mains frequency meter for 220 V. The world's first public electricity supply was a water wheel driven system constructed in the small English town of Godalming in 1881. It was an alternating current (AC) system using a Siemens alternator supplying power for both street lights and consumers at two voltages, 250 V ...
Adelaide: part of the suburban network (50 Hz). Commonwealth of Independent States: parts of the network (50 Hz). In Finland: see rail transport in Finland (50 Hz). In India: see rail transport in India and Central Organisation for Railway Electrification (50 Hz). In Spain: the Atlantic Axis and the Madrid-Galicia HSL between Ourense and ...
AC power is used at 60 Hz in North America (excluding the aforementioned 25 Hz network), western Japan, South Korea and Taiwan; and at 50 Hz in a number of European countries, India, Saudi Arabia, eastern Japan, countries that used to be part of the Soviet Union, on high-speed lines in much of Western Europe (including countries that still run ...
Availability Based Tariff (ABT) is a frequency based pricing mechanism applicable in India for unscheduled electric power transactions. The ABT falls under electricity market mechanisms to charge and regulate power to achieve short term and long term network stability as well as incentives and dis-incentives to grid participants against deviations in committed supplies as the case may be.
576i is a standard-definition digital video mode, [1] originally used for digitizing 625 line analogue television in most countries of the world where the utility frequency for electric power distribution is 50 Hz.
