Distance between Extra high voltage transmission lines and residential buildings

the minimum distance that has to be maintained  from the base of pylon/tower to any nearest residential plot


That is more complex, as the buildings may be built nearer if extra precautions are taken with  metallic services, pipes and things like phone lines etc, so that any EHV fault or lightning induced current does not cause the property to rise in voltage relative to the rest of the earth by some amount.


What can be done at what distance is site specific advice,  and usually involves  survey and some sums.


You'd not normally want residential structures because of considerations of noise and visual impact, as well as possible TV and Radio interfernce from insulator discharges, and  the lines will need periodic access for maintenance.

The pylons are better offset from  the development, so folk see the wires but the pylons proper are obscured by buildings, and as far as possible the lines run over agricultural land or parks or similar, where no one sleeps and vehicles can be got in quickly if need be.
