POWER FAILURE IN EAST ANGLIA

CliveS
What happened?   Why did the grid cascade trip and not isolate the immediate network?  Natgrid is NOT responsible for failure of British rail or hospital emergency supplies and MUST NOT fiddle the protection around trying to keep key areas/cities railways on!! 

Just shed the immediate area in this case Norfolk and Suffolk.  We do not need an expensive legal inquiry or someone to blame;  just reset the protection and shed the nearest area to the fault.  Sorry for the RANT.

    Switzerland is fairly self sufficient for electricity at the moment with a mixture of Hydro and Nuclear (the Greens are trying to upset this but that's another story). The Swiss Railways have their own Hydro stations and grid running at 16 2/3 Hz with some converter stations to take additional power from the 50 Hz grid.

    A significant quantity of electricity passes through Switzerland, Italy was blacked out a few years ago due to failure of some trans alpine interconnects in a storm but the lights stayed on here.


    Best regards
