Here's a couple of pics of a Pole-top Transformer that I had to work on last week.






This is a 50kVA 22kV Primary - 400/230 Delta/Star type.
It's an end of line transformer or Spur Line transformer, as we call them, the HV fuses being at the supplying end of the Spur, about 200 metres away.
In the first pic, just in behind the tranny itself, is the LV connections and the Neutral(Star) point.
The transformer has it's Neutral Earthed at this terminal(along with the Service Line Neutral), via a heavy (16mm) wire running down to a whopping great Earth spike in the ground that is driven with a stake driver.
