60hz frequency or 50hz?

[Cerise]

hi does anyone have an idea why some countries chose 60hz as their standard operating frequency? does it have advantages? please help.. i need it for our research. it will also be of great help if you can give some examples and comparisons to 50hz frequency..thank you very much!

i have to defend that 60Hz is better.. can you give me some tips on how can i defend it?

Most of the contries use 60Hz the mains supply is usualy 120v and for 50Hz it is 220v,i think 60Hz is used to reduce power consumption from power station also it's more safe to operate in a low voltage.

Is it true that 60hz frequency is used for power consumption or there is any other reason behind it.

Although there have been technical reasons behind the decision for 50 or 60 Hz, it's mainly a historical discussion. For obvious reasons, noone intends to change the national standards now. You'll find pros and cons for both standards. Depending on your industry and field of application, one or the other matters more. In addition, you have 16 Hz in railway traction or 400 Hz for aviation board supply.

can you please state some of the pros of 60Hz?

 

[FvM]

First of all, transformers and AC motors can be smaller by 1/6. For the same reason, 400 Hz is used in aviation.

At 6oHz transformers are smaller but transmission losses over long cables are higher. Motors are also smaller (and faster) at 60 Hz.
