In view of Eskom’s current network expansion at 765 kV, it was necessary to address occupational exposure of substation workers to electric fields, particularly in 765 kV substations with busbar height of 12 m. This paper reports on the assessment of 50 Hz electric field levels that substation workers may be exposed to in 765 kV open air substation.It was found that at 12 m busbar height, at 800 kV line voltage, the maximum calculated electric field, 21,9 kV/m, exceeds the International Commission for Non-ionising Radiation Protection (ICNIRP) reference level (20 kV/m) at two locations covering a small area… ( more)
