Why 50hz frequency supply in India?

Answer 1

60Hz was originally chosen in the US to help market AC power systems to customers. The ploy was that a clock could run using a synchonous AC motor and at 60Hz, the gear mechanism would be greatly simplified. Then the job of keeping accurate time fell to the electricity company by maintaining a constant frequency. Prior to this, many different frequencies had been tried.

In India, it is a decendent of the British Imperial system.

Technically speaking operating a transformer on 50 Hz versus 60 Hz would not make much difference, as long as you ar e careful to avoid over fluxing the transformer core.

Answer 2

There are no sensible technical reasons to have to do anything to change the electrical power distribution network in India to 60 Hz because its present 50 Hz system works perfectly well.

Many other countries of the world use 50 Hz instead of 60 Hz and the only reason to discuss whether there should be a changeover is principally a matter of government/ political debate.

The answers to the Related Questions, shown below, give more information about the reasons for the existence of both 50 Hz and 60 Hz electrical power distribution networks in the world.

Another answer

Do you have an appliance that does not work properly at 50 Hz?

- If it is a device designed to run on 60 Hz it usually has to be modified to run on 50 Hz. Remember that the voltage has to be changed too.

- For an electric clock, the answer is to get another clock. The gear ratio would have to be changed.

- For a phonograph or tape recorder, the motor pulley is usually exchanged for one calibrated for 50 Hz.

- Most electronic devices (radios, amplifiers, computers) do not have to be converted, but some with an undersized power supply could overheat or hum at 50 Hz.

- Power tools run a little slower, but should work if converted for voltage.

- Light bulbs can't tell the difference in frequency.

- Anything with an AC adaptor can probably be run with an equivalent adaptor sold by the company for the purpose.

Answer 3

because induction motor has best efficiency between the frequency ranges of 50-60Hz. And induction motor is mostly used bcz of its high efficiency.......we choosed 50Hz because of its cheaper in applying over the various power application.

Answer 4

It would be very expensive to replace all 50Hz equipment with 60Hz equipment. No one wants to foot the bill to change. People in India can just as easily say "Why can't the US change to 50?".

Answer 5

Because in the UK the frequency of power supply is 50 Hz and UK start the electricity in India so frequency of power supply in India is 50 Hz.
