That limitation is a little bit arbitrary - 110/240 are stepped down, post-transmssion voltages. In terms of interconnection/transmission between states there are ways around this. 50/60Hz poses a little bit more of a difficulty, perhaps... I'm no electrical engineer but there are apparently (inefficient?) ways to do this.
- Leynos 16y agoJapan seems to overcome the frequency issue somehow: https://secure.wikimedia.org/wikipedia/en/wiki/File:Power_Grid_of_Japan.PNG https://secure.wikimedia.org/wikipedia/en/wiki/File:Power_Gr... Half of the country operates at 50Hz and the other half at 60Hz: "In Japan, the western part of the country (Kyoto and west) uses 60 Hz and the eastern part (Tokyo and east) uses 50 Hz. This originates in the first purchases of generators from AEG in 1895, installed for Tokyo, and General Electric in 1896, installed in Osaka. The boundary between the two regions contains four back-to-back HVDC substations which convert the frequency; these are Shin Shinano, Sakuma Dam, Minami-Fukumitsu, and the Higashi-Shimizu Frequency Converter."
- fr0sty 16y agoThis has actually been a major issue in light of the recent damage from the earthquake/tsunami. Poser generation on the 50hz half of the country has been greatly diminished and the frequency matching stations have insufficient capacity to meet demand. http://www.npr.org/2011/03/24/134828205/a-country-divided-japans-electric-bottleneck http://www.npr.org/2011/03/24/134828205/a-country-divided-ja...
