Original Abstract

The paper is focused on the measurements of high temperatures related to electric low volt-age apparatuses switching off process. An optical emission spectroscopy was used for these measurements, because the optical emission spectroscopy is one of best methods for obtain-ing 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 elec-trodes 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 elec-trode temperature using Planck function.
