Abstract
Mjerna nesigurnost je jedinstven, univerzalan i jednostavan iskaz o kvaliteti mjernog rezultata, odnosno mjerna nesigurnost predstavlja raspon vrijednosti unutra kojih se očekuje da se nalazi prava vrijednost mjerene veličine. Da bi se odredila mjerna nesigurnost, potrebno je obaviti niz mjerenja. Za određivanje mjerne nesigurnosti karakteristike nelinearne zavojnice potrebno je izmjeriti tri parametra: napon, struju i snagu. Prilikom mjerenja važno je obratiti pažnju na utjecajne veličine i pogreške prilikom samog procesa mjerenja. Na temelju dobivenih parametara izračunavaju se lomne točke i područja pouzdanosti lomnih točaka. Nakon analize podataka uočeno je na koji se način ponaša karakteristika s obzirom na broj provedenih mjerenja, odnosno broj lomnih točaka. Kako se broj točaka karakteristike smanjivao, tako je ona gubila svoj prvobitan oblik. Smanjenjem broja mjerenja, odnosno kako se smanjio broj lomnih točaka tako se smanjila nesigurnost karakteristike, ali samim time se i smanjila glatkoća karakteristike

Measurement uncertainty is unique, universal and simple statement of quality of mesurement result, respectively mesurement uncertainty shows the range of value in which the accurate of measured size is supposed to be found. It takes number of measuring to determine measurement uncertainty. To determine measurement uncertainty of nonlinear coil it is needed to measure three parameters, voltage, current and power. During the measurement it is important to pay attention on influencig factors and mistakes during the process. Based upon the obtained results fracture points are being calculated and the field reliability of fracture points. After data analysis it is observed how the characteristic behaves considering the number of measurement, respectively number of fracture points. With the decrease of number of measurement, respectively the number of fracture points decreased and the smoothness of the characteristic, and with that the measurement uncertainty went up.
