“…The previous studies did not take the uncertainty in conductor heights into account. Thus, the uncertainty in heights of OLs was removed by examining the effect of the height on EM calculation results by the image charge method in two dimensions [23]. However, none of the above studies examined the effect of the uncertainties in frequency, ground resistivity, conductor characteristics, and transmission line structures on self-and mutual impedances of OLs with equilateral and inequilateral conductor dispositions.…”

This paper presents a method that finds the expected values of self-and mutual impedances of overhead lines with the uncertainties such as the ground resistivity, conductor characteristics, and transmission line structures. For this purpose, this study designs a stochastic random sampling method that removes the uncertainties. A finite element analysis method that includes a single logarithmic closed-form solution to Carson's improper integral is adopted. The impact of an increase in sags and an imbalance in phase conductors on self-and mutual impedances is examined. As a result, the expected values of the selfand mutual impedances of an overhead line are evaluated. It is also shown that as the sag ratio increases, the self-and mutual impedances decrease.

“…When calculations of electric field intensity and magnetic flux density of overhead transmission lines in operation are performed, for some precisely determined conditions, the applied voltage and current values are obtained using voltage and current measuring transformers. Thus, these values are accompanied by measurement uncertainty that depends on the accuracy class of the instruments [15], [22]. The geometry of the overhead transmission line, and specifically the conductor heights are obtained by measurement.…”

This paper presents a new approach for uncertainty determination of the electric field intensity and magnetic flux density calculation in the vicinity of overhead transmission lines. The proposed method is based on the law of propagation of uncertainty as defined in the Guide to the expression of Uncertainty in Measurement. A mathematical model is developed for determining the electric field intensity and magnetic flux density calculation uncertainty based on the Charge simulation method and method based on Biot -Savart law, respectively. The verification of the proposed method was performed by estimating the uncertainty of the electric field and magnetic flux density calculations for four single circuit and two double circuit high-voltage overhead transmission lines. The analysis of the obtained results demonstrates that the proposed method can be successfully used to determine the uncertainty of electric field intensity and magnetic flux density calculations in the vicinity of overhead transmission lines.
