Mains frequency

Kelly Marie Angel
Just checked the dynamic demand site and the frequency was down to around49.7 cycles almost down to the lower legal limit never seen that before

    The gridwatch site only updates very slowly and this number seems to be hugely smoothed. The DD site is interesting, and pretty much matches some other results I have with a similar resolution. Grid is slow this morning and there is coal in use as well. 41.35 GW is coming well towards max availability, all we need now is a power station problem!

    Dynamic Demand page

    Does need Java to be allowed (at least for that site) - hence iPad's etc won't work.


    and is still hovering low...

    would correlate with the Red 'average' ? line on the other GB Frequency site ?

    Hi Andy the sight I saw it on is called Dynamic Demand when you open it click on the little picture of a frequency meter and that takes you to the real thing. It doesn't work on my tablet but is fine on my fone

    Where did you see that? It doesn't seem to show up on GB Grid Frequency - I wonder if it was just a glitch somewhere in the internet, rather than real world.


    I did stumble on an interesting use for mains hum though - BBC News: The hum that helps to fight crime (an old story, but one I'd missed before)
