The turbines were slower and a lower frequency meant you didn't have to build so many poles into the machine. I don't believe flicker was an issue since that actual cycle of dim-bright is twice the electrical frequency as the filaments will heat up every half cycle.
When generation became more common in cities it was almost always steam turbine driven and tended more to higher frequencies. Higher frequencies don't require as much iron in transformers as the flux has less chance to build up. AC distribution on airplanes is sometimes Hz to keep the weight of transformers down. Higher frequencies lower the ampacities of cables due to skin affect, and overall impedance is higher for the same line inductance when the frequency is higher. Of course one could debate the optimum Hz value for each situation, but it is more important to stick to the standard that has been agreed on.
The driving force in the nineteenth century that determined the supply frequency was to balance efficient distribution against the needs of traction. The heating effect of wound components in motors and transformers demanded large metal frames to dissipate the heat.
The limiting factor being the melting point of the insulating varnish. The world's main supplies electricity AC voltages are different from countries to countries, generally are V V and V V, V. The operation frequency is typically 60Hz at v in Can a v appliance work on v in US? Did you find the content in this article useful? Explore the rest of our website for more insights!

With 50Hz, voltage bounces between positive to negative, and then negative to positive voltage. The voltage changes in a similar way to 50Hz. Why do some countries use one type of Hertz over the other?
Here are some of the major differences you should know about. In general, 60Hz systems tend to use more voltage for the domestic power supply than 50Hz.
Voltage Converters. Soft Starters. Why the frequency of power supplies in European and Asian countries is 50Hz, while American countries use 60Hz power supplies? What is the basic of the standard? What are the advantages and disadvantages of 50Hz and 60Hz power supply? In addition, why the airport and aircraft use Hz frequency? In fact, there is no big difference between 50Hz and 60Hz , only the generator speed has slightly difference.
Choose 50Hz or 60Hz, it's almost always the same in a country except Japan Japan has both 50Hz and 60Hz power supplies.
We should be aware that why use 50Hz or 60Hz, rather than lower or higher frequency. In electrical system, frequency is a very important basic element, not arbitrarily determined. It looks like simple, but in fact, it is a much complex issue, involve with many aspects. From the principle, we should mention the classical electromagnetic theory found by Maxwell, Hertz added a critical point for Maxwell's theory, Faraday's law of electromagnetic induction and the world's first electromagnetic induction generator, the British engineer Ward King made the electromotor first, the French Pixie made generator, Siemens found the generator principle, the invent the power generation machine, which is the first case in practical application.
Since then, it was found and summed up the theorem that the cyclical changes in the direction of the current is called alternating current, the time of the current in one cyclical change called the cycle, the cycle times of the current changes in one second called frequency, the unit is Hertz in order to commemorate the contribution of German physicist Heinrich Rudolf Hertz. The frequency of alternating current is 50 60 Hz, the current direction changes 50 60 cycles, times per second.
The electric motor is made according to the basic principle of the rotating coil in the magnetic field. If connect two copper slip rings respectively to the ends of the motor coil and two brushes connect with the slip rings, it becomes an alternator principle. Generator is a device to achieve the conversion from mechanical energy to electrical energy.
