   from left to right: disconnect switch, on top of the pole, the big box   
   with two "antennae" potential transformer, below the big barrels current   
   transformer, next pole big barrel with two "antennae" isolation switch.   
   this supplies a "big box" shop that sells white goods (washing machines   
   and the like) I couldn't take a photo of the meter as there was a large   
   truck in the way. of course the current transformers need their   
   secondary short circuited. and of course this metering method works only   
   in three phase systems without a neutral.
