It describes the properties of the universal Pentegov model, employing any shape of static voltagecurrent characteristics of an arc. Next, it presents spectral and integral measuring methods for determining arc parameters in the Mayr, Cassie and Pentegov models of the electric arc with a forced sinusoid current circuit, with the raising static characteristics of hyperbolic-flat and hyperbolic-linear shape. The influence is discussed of the random power supply disturbances on errors of determining the mathematical model parameters.}, type={Artykuły / Articles}, title={Spectral and integral methods of determining parameters in selected electric arc models with a forced sinusoid current circuit}, URL={http://ochroma.man.poznan.pl/Content/85183/PDF/DOI%2010.1515aee-2016-0007.pdf}, doi={10.1515/aee-2016-0007}, keywords={electric arc, Mayr model, Cassie model, Pentegov model, spectral methods, integral methods}, }
