Distance between Extra high voltage transmission lines and residential buildings

Hi all,


I have a querry regarding the Extra high voltage transmission lines (EHV AC)


I would like to know the international standards for maintaining a safe distance from overhead transmission lines of 132 KV & 400 KV passing by residential plots where the cluster of residential high rise/super high rise towers are planned to be executed.


Appreciate advices from experts


Thanks & Regards

    Mind you not all pylons / towers near houses actually are EHV.
    this and this  are opposite ends of the same span - the really small (all things relative...) insulators tell us it is not as EHV as we think, just made up extra tall to get up and over the housing estate. They do not buzz like the higher voltage cousins.

    Mind you , I have no idea how common that sort of trick is.

    Similarly this is only 33 kV as evidenced by both the insulators and the 1950s signage. Drops down to wooden poles a mile or two away here. It would in fact appear to interconnect with the one you mentioned.


    I'm unsure if there was an intention to upgrade it later, the pylons would appear to be designed to allow either the 6 cables to be much more widely spaced than they currently are, or perhaps to double-up to four 33 kV circuits. Who knows.
