Why is power at 60Hz?

Why is power at 60Hz?

Why is 60Hz frequency used in America instead of the 50Hz used in most of the world? The use of 50 versus 60 Hz is purely due to historical reasons, with companies in the US making 60 Hz equipment and those in Europe making 50Hz equipment so that they have a monopoly. This rivalry led to the split you see today.

Why does public power use 50 Hz and 60 Hz?

$\\begingroup$ The main reason is to avoid visible flickering of light. Another reason is transformer-cores… Lower frequency, would require more iron and thus larger transformers. With a higher frequencies, everything electrical would make a (more) audible hum (50Hz is at the limit of the human ear).

Is the 60 Hz power line frequency accurate?

The 60 Hz power line frequency is known to be relatively stable. The integrated frequency, or time-keeping aspect of frequency, is also quite accurate. This is why AC electric wall clocks keep exceptionally good time.

Is it OK to have a wall clock at 60 Hz?

The answer depends on how close you look; over what time span you average. I know of no electric appliance that cares if the frequency is 59 Hz or 60 Hz or 61 Hz. With the exception of a wall clock, perhaps even as low as 50 Hz or as high as 70 Hz is ok.

Can a 50Hz motor work at 60Hz?

On electronics with motors that turn or vibrate, frequency will determine the speed at which they operate. Some devices will indicate 50/60Hz, which means it can operate at either 50Hz or 60Hz and perform well. However, many devices are designed for only 50Hz or only 60Hz, but not both.
