HV code 3

lyledunn

If 7671 applied to HV and DNO equipment, might this be a code 3 if subject to periodic inspection? It is an 11KV pole on  next to my house  on land which was abandoned following failed planning permission for two houses. Following my notification of the possible danger of land slip, the DNO said it looked stable and they didn’t have concern. The photo below is the situation that prevailed when I notified them last year.

    It'd hard to be sure from the picture - I'm guessing the exposed soil is a "cliff" formed when the foreground was levelled?

    If so how far away/above is the base of the pole from the base of the "cliff"? (I'm thinking that the general rule for supporting ground is that it needs to extend at 45 degrees from the base (i.e. if the horizontal measurement exceeds the vertical one, you're probably OK) - although it might want to be a bit further in this case to counter the tendency for the pole to lean in the wind, but you could knock a bit off to account for the depth of the pole. So one unknown vs another.

    I have to say that DNOs seem to have a pretty good record of planting poles into pretty steep hillsides around here.
