Re: " 220V on which South Korea operates"
A few years ago the village where I live was having some major work done on the electricity infrastructure, so a massive generator was brought in to run everything. Power quality was really good, no brown outs or anything, but I did notice that clocks on things like the VCR (yes, this was a few years ago) the cooker, etc. were running fast. That was when I learned that (a) some digital clocks synch to mains power cycle, (b) some generators run faster than 50Hz
