One day John and I were driving home from Franklin, New Hampshire and I was holding my new Olympus Stylus Touch 8000 out of the window as I tried to learn its functions. We drove by this electrical substation and I actually got a well framed shot. I have always had a fascination with these substations but have never taken the time to learn about them. I read a little from
Wikipedia tonight.
Where a substation has a metallic fence, it must be properly grounded (UK: earthed) to protect people from high voltages that may occur during a fault in the network. Earth faults at a substation can cause a ground potential rise leading to a significantly different voltage than the ground under a person's feet; this touch potential presents a hazard of electrocution.
