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.
