There's a long and ugly history of why we have such a low frequency for power distribution. Be glad its not 15Hz or lower!
I'm familiar with some of it. How higher frequencies were better for lighting, but lower frequencies were easier to generate at the time, power line vs iron losses, etc. Incidentally, at one time 25 Hz power was common in North America. That came about because of the first generating plant at Niagara. When they decided to go with AC, a lot of the mechanical details, such as turbines had already been fixed and they were pretty much limited to 25 Hz AC. It wasn't that long ago, that the last of the 25 Hz generation at Niagara was shut down. However, there were a lot of different frequencies used years ago. Also, in Newfoundland, there were some parts of the province on 50 Hz, with the rest on 60. I believe that situation still exists in Japan. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
