Abstract
Nelinearna zavojnica modelira se otporom i induktivitetom čije su karakteristike linearne po odsječcima. Parametri karakteristika se određuju na temelju mjerenja napona, struje i snage. Kako sva mjerenja posjeduje mjernu nesigurnost promatra se njihov utjecaj na parametre karakteristika otpora i induktiviteta. Procjena mjerne nesigurnosti parametara karakteristika temelji se na pretpostavkama da se mjerne pogreške izmjerenih veličina mogu opisati normalnom razdiobom i da se može primijeniti linearizirani matematički model. Na temelju provedene analize uočeno je kako dolazi do znatnog povećanja mjerne nesigurnosti karakteristika s porastom napona. Najveći doprinos mjernoj nesigurnosti karakteristika dolazi od mjerne nesigurnosti izmjerenog napona.
Abstract (english)
Nonlinear coil model is defined by piecewise characteristics of resistance and inductance. The characteristics of coil are obtained by measurements: RMS coil voltage, RMS coil current and coil losses. Since every measurement has uncertainties, it is investigated how measurement uncertainties reflect on coil characteristics. Estimation of coil characteristics uncertainties is based on following assumptions: all measurement errors have normal distribution and linearized model is sufficiently accurate approximation of nonlinear coil model. Results show that uncertainty of coil characteristics is growing for higher amplitudes of voltage. Highest contribution to coil characteristics uncertainty has uncertainty of measured RMS voltage
