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.

    If it was my Scout Hut and the external walls were metallic I'd be concerned about touch potential - the voltage between the feet and the hand of somebody's child standing on hard ground and leaning against the building.  I'd address this with a buried earth tape bonded to the building steelwork run around the outside of the building about 1m out and 0.5m deep.
