Sažetak
U radu je prikazan postupak merenja fazne razlike izmenu dva sinusna električna napona koristeći metodu tri voltmetra. Merna nesigurnost rezultata merenja fazne razlike procenjena je na dva načina: u skladu sa Uputstvom za izražavanje nesigurnosti u merenju (GUM) i u skladu sa Dodatkom 1 GUM - Prenos raspodela korišćenjem metode Monte Karlo. Upoređeni su dobijeni rezultati za mernu nesigurnost.
Abstract
Phase difference measurement between two sinusoidal electric voltages using three voltmeter method is presented. Uncertainty of phase difference measurement is evaluated in two methods: according to Guide for expression of uncertainty in measurement (GUM) and according to Supplement 1 to GUM - Propagation of distributions using a Monte Carlo method. Those results for measurement uncertainty are compared.
