Pole.

I am asking this on behalf of a friend. A young mum with toddlers that use the back lawn is concerned about the pole. The overhead supply comes in on A.B.C. cables and the pole being the last in the run has an earth electrode at its base. The pole is situated in a boundary hedge and the toddlers, over bare footed on the ground, can walk with 0.5 metres of the earth rod.


Are there any safety concerns here please?


Concerned of Peckham.

    I'll go for a flippant remark since it's the weekend.


    Is there more of a risk in kids near 11 kV overheads growing up to become little *******s and throwing stones at the insulators until they break?


    You never did? Did you?

    Regards the pole earth, any voltage on it will almost certainly be the same as the voltage on all the earthed metal work in and around the house.


    But the young mum is more concerned about the stray Voltages roaming about on her lawn, under the pole,  near the end of run earth electrode, where her young children play bare footed.

    No ... but probably only because there are no overheads where I grew up.


  • under certain situations a pole can give real trouble,  luckily that sort of thing is rare.


    That was impressive!

     



    I just watched that video scary what can happen what I want to know why didn't the substation fuses blow?

    My guess would be that it was one of the old pitch filled sealing boxes (on the end of an PILC cable) so the arcing was through something akin to carbon char rather than a nice dead short metal-to-metal of negligible impedance so the fault current was limited and likely quite short for each individual 'crackle' event.


    Maybe someone's found an application for AFDDs after all....

    Yeh, we had to climb trees, go for bike rides or kick a tin can about as well.

    There are no piles of dead sheep at the bottom of the pole.


     


    Is that because she lives on the High Street Chris? Or do the locals immediately grab the dead sheep for a Sunday stew??




    Please see 10.23 ref sheep.
