Abstract |
Sections cover: physics of electrical and magnetic fields; instruments and methods for measuring field intensity; results. These show that electrical field intensities, measured 1.8m above ground under overhead lines, depend on the voltage level, the height of the lines above ground and the type of pylon. Field intensity may be as high as 6kV/m in the case of a 420kV line 11.5m above ground (the natural atmospheric electrical field intensity being only 0.13kV/m). Intensity falls exponentially with increasing line height. Measurements at 1.8m above the ground in 420 and 300kV substations showed maximum intensities of 11kV/m and 6.4kV/m at a distance of 2.5m from the disconnecting switches. |
