Steel Clad Building and High Voltage Overhead Cables.

Zoomup
Views invited please.


There is a modern sheet steel clad building nearby. It has what appears to be plastic covered steel sheets as exterior walls. It is used as a Scout Hut and can probably accommodate about 80 people for events. Running overhead are three high Voltage cables that feed local transformers, including the scout hut transformer which is on a pole nearby. The scout hut has two earth electrodes which connect to a part of the building and earth it. Although they are quite close together so may not really count as two in function.


Theoretically what would happen if one of the H.V. overhead cables came adrift and fell onto the roof of the building regarding risks?


This is a theoretical question relating to a real building but with a serious intention.


Thanks,


Z.

    Downed bare HV cables onto hedges etc are normally dead soon after landing.




    The worrying word here is 'normally'. I am aware of a case, a number of years ago now near where my mother grew up (S. Glos), of the son of a farmer who was in his tractor in a field using the hedge trimmer attachment when it met a downed HV cable which unfortunately was not dead.....
