Sažetak
The aim of this paper is to present some aspects of the evaluation of uncertainty in measurement of electrical energy on high voltage transmission lines. It is made in accordance with the Guide to the Expression of Uncertainty in Measurement. The mathematical model includes voltage and current instrument transformer parameters, watt-hour meter parameters, load of the low-voltage circuits of the instrument transformers, and impedance of the cables connecting the instrument transformers with their loads. Our most specific problem was how to present the result of measurement of energy because its uncertainty cannot be characterised by a unique value. It depends on several parameters. The most significant parameters are current and power factor in transmission lines. Some solutions in presenting results are given.
