The Big apple State General public Services Fee done a examine[forty nine] To guage prospective health effects of electric fields. The study calculated the electric industry toughness at the sting of an current ideal-of-way over a 765 kV transmission line. The sector strength was 1.six kV/m, and became the interim greatest energy standard For brand new transmission lines in Big apple State. The view also confined the voltage of new transmission lines in-built Ny to 345 kV.
