This paper presents the study of assessment of
external electric and magnetic field exposure to live line
operator of 1200 KV, Ultra High Voltage (UHV) AC proposed
line in India. Single circuit (S/C) and double circuit (D/C)
power lines are considered for the assessment. Combination
of charge simulation and image method is adopted for
evaluation of extremely low frequency (ELF) electric fields
where as Ampere law is used for magnetic fields. Analysis is
carried out using MATLAB software . The assessment of ELF
exposure to line operator has been carried out for various
scenarios. These assessed values of electric and magnetic field
(EMF) exposures are compared with standard allowable limits
set by various International Standards. Moreover, the safety
of general public living at the edge of right of way (ROW) and
15 m away is evaluated. The objective of the study is to create
awareness about the power frequency EMF radiations and its
health issues among the power engineers, line operators ,
general public’s and to electricity utilities, the government to
enforce the regulations.
