Dva postupka procene merne nesigurnosti rezultata merenja fazne razlike metodom tri voltmetra
Ključne reči: fazna razlika; metoda tri voltmetra; merna nesigurnost; GUM; Dodatak 1 GUM
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.
