This article presents a detailed analysis of uncertainty estimation of loop impedance measurement determined by the vector method. The analysis includes the following estimates: resistance variance, voltage variance and time measurement variance. This paper presents a methodology for estimating the combined standard uncertainty of loop impedance by the vector method. The vector method allows to determine loop impedance based on the orthogonal voltage components, which makes a loop impedance measurement much more accurate than in case of conventional methods. The estimated value of the combined standard uncertainty uc, confirms that the vector method is more accurate than classical ones.
