Which One is the Best System...60Hz or 50Hz,,,and Why?
Please Answer it with appropriate reasons and reference..Thanks

 

So you want us to supply your homework answer. It doesn't work that way. You need to do some research on you own and then ask questions about that, if you still have some.

 

the main difference is that the transformers and motors are heavier in 50 hz systems, more iron needed. thats one reason aircraft went to 400 hz, much lighter transformers and motors on 400 hz. iron core losses lower.

 

I recommend looking up the term "Hysteresis". It will give you an idea of one of the main, practical differences between the two. Start from there.

And as previously mentioned, we are not an answering service. YOU must do the work. We can only point you in the right direction.

 

This actually makes interesting reading ....

Sounds like the early days in power generation & distribution boasted a veritable frequency zoo.

Years ago, read an article about when the state of California standardized the line frequency. There was a statewide program to modify electric clocks to work at the new frequency. Not just the state-owned clocks, but all clocks!

I think this story was in American Heritage of Invention and Technology magazine. I really miss this magazine.

Og God...You are so funny...
And thanks to all for helpful Answers..
Once again thank a lot.

 

60 Hz is better because you can easily build a synchronous motor for a clock with it.
400 Hz is better because you can make a 5 horsepower motor small enough to pick up with one hand.
50 Hz is better because it has less radiation losses in long transmission lines.
25 kilohertz is better because humans can't hear it if it radiates into their audio amplifiers.
440 Hz is better because you can use it for tuning your musical instruments.

 

60Hz is better because all my clocks would not keep proper time.

50HZ would work for me. I like to be fashionably late.

Yep. It's a real hoot when someone is expected to put in some effort on their own. What a riot! They should make a sitcom based on it.

 

 

As I grew up, I learned of something called a "work ethic".
I even got a part time job when I was sixteen and bought my first car with the money .. go figure.

edit: just Venting ...

 

Bundle of Thanks for reply and informaton... Once again Thanks all..

your body has some natural "oscillations" around 60 hz, which is one of the reasons they decided to go with that frequency for safety. It really doesn't matter a whole lot whether your using 50 or 60 hz, most devices that arent a simple load like a motor or lightbulb always use a diode bridge to some dc voltage with a capacitor so the ac frequency doesnt make any difference

Please provide some decent references to back up this claim.

 

Just put your finger on a scope probe and you will see the 60Hz waves. They are only 50 Hz in Europe because of jet lag.

 

Somebody thought that since there are 60 minutes in an hour and 60 seconds in a minute, why not have 60 cycles in a second.
