A few years ago, the The Tesla Coil Builders Of UK (TCBOUK) had a visit the
the electricity boards test lab facility in Leatherhead, Surrey.
It may be worth a call to them and see if you can get a visit.
They should be able to answer all of your questions and more.
They have in addition to what you'd expect, the most massive Marx generators
I've ever seen.
We're talking building sized.
Of course, If you're a terrorist, then they might ignore yor request
entirely.
Cheers.

I am doing some research on the UK Electrical national gird system and
looking for lots of info.

I am after stuff like national layout, means of control and power
regulation, safety issues/procedures, transmission voltages and the like.

Much appricated any info or web links.

Thanks in advance,
