Experimental Measurement Of Radial Temperature Distribution Of DC Arc
MetadataShow full item record
The paper is focused on an electric arc spectroscopy diagnostics related to electric low voltage apparatuses. Measurement of radiation spectra of the electric arc burning between carbon electrodes with cooper admixture is presented. Cooper has a lot of suitable atomic spectra lines for calculation purposes. The problems connected with the measurements are discussed. The main part of the paper deals with a calculation of radial temperature distribution of the arc. Abel inversion was used to extracts the radial (2D) distribution from a one-dimensional projection measurement. Atomic lines database of National Institute of Standards and Technology was used as a spectral data source for the calculations.
