Abstract

The paper is related to the assessment of exposure of the general public to extremely low-frequency electromagnetic fields in the vicinity of transmission overhead power lines, based on measurements and calculations of electric and magnetic fields. The uncertainty of electric field strength and magnetic flux density measurement and calculation results is evaluated for a typical 220 kV overhead power line. The most influential uncertainty components and the expanded uncertainties are analysed in detail. Measurement results obtained with two different electromagnetic field analysers are compared with calculation results. Compliance between these results is verified using the  number and  value. The analysis confirms the validity of both the obtained results and the evaluated expanded uncertainties. The study demonstrates that measurement and calculation uncertainties must be properly considered when assessing compliance with exposure limits. The presented methodology provides reliable results and is particularly important for the accurate evaluation of public exposure to electromagnetic fields, and for demonstrating compliance with the prescribed reference levels.
