Any Electricians ?

[Mark Hennessy]

Hi Al,

Thanks

I agree that Wikipedia article could be clearer - perhaps we should update it . I think I'd be happier with the IT diagram if the source was drawn in Delta configuration, but I guess they were trying to keep things simple as earthing was the main point they were trying to get across.

But yes, it's quite common to take one or more 11kV feeds and step them down on site - we do routinely.

All the best,

Mark
