Overhead power line height rules need safety update, say farmers

Sparkingchip

The news report is behind a pay wall, but you'll get the gist of it, farm equipment is a lot bigger than it used to be particularly booms on sprayers and the like. 

So maybe it's time to increase the clearance of overhead electricity cables.

    Easy as it is to put this on the network operators, is this really an issue with the OHLs?

    For LV installations in agricultural premises, where the  limited to 1 kV AC, experts agree (and hence it's a BS 7671 requirement) that the conductors ought to be both insulated, and installed with a minimum height of 6 m.

    There are only two possible conclusions, either:

    1. The heights in the ESQCR are out-dated, as is the fact that OHLs at lower heights have no insulation; or
    2. The requirement in BS 7671 is over-prescriptive.
