Abstract: The paper is focused on the measurements of high temperatures related to electric low voltage apparatuses switching off process. An optical emission spectroscopy was used for these measurements, because the optical emission spectroscopy is one of best methods for obtaining a temperature of high temperature objects. Experimental measurement of radiation spectra of electrodes among which an arc was burning is presented. Electrodes was made of carbon with stabilisation core with potassium and sodium admixture. Radiation spectrum of electrodes was close to the black body radiation spectrum. The problems connected with the measurements are discussed. The main part of the paper deals with a calculation of the electrode temperature using Planck function.
Keywords: DC arc; high temperature measurement; optical emission spectroscopy; Planck law
