All,
If you want a reason for logging the mains frequency, see the following
link to a news item which appeared on a BBC news program a few weeks ago
here in the UK.

There was also a full program about it which you can listen to at the

Interesting. I never realized the UK national grid was just one grid, all
running at the one frequency.
I wonder if there are small variations in frequency at a local level due to all
these wind-turbines that seem to be cropping up everywhere? I doubt they will
generate a voltage at exactly the same frequency the voltage is coming into
them, especially as it is not a constant.
I personally object to funding these things so others can make a huge profit
from them. Perhaps I can argue they are a threat to national security!
