“…Development of vacuum circuit breakers raised interest to systematic spectroscopic investigation of the vacuum arc between Cu and Cu-composed electrodes. Spectroscopic investigations of the vacuum arc with Cu electrodes are presented in works, [10][11][12][13][14][15] where plasma parameters were determined. The number of publications dealing with Cu spectra description is rather limited.…”

“…The number of publications dealing with Cu spectra description is rather limited. 10,11,13,[15][16][17][18][19] Most of them have been studied under low current conditions, 100-400 A (Refs. [16][17][18][19] and 20-1000 A.…”

“…Spectroscopic methods for HCVA investigations were applied in order to obtain the excitation temperature of Cu I, Cu II by several authors. 10,13 For the application of the plasma characterization methods based on OES spectral line identification should be performed primarily. The Cu spectrum is densely populated with lines and contains many transition in abundance, [20][21][22][23][24][25] which often is the reason for overlapping of the lines and makes the line identification challenging.…”

Spectroscopic investigations of free-burning vacuum arcs in diffuse mode with CuCr electrodes are presented. The experimental conditions of the investigated arc correspond to the typical system for vacuum circuit breakers. Spectra of six species Cu I, Cu II, Cu III, Cr I, Cr II, and Cr III have been analyzed in the wavelength range 350-810 nm. The axial intensity distributions were found to be strongly dependent on the ionization stage of radiating species. Emission distributions of Cr II and Cu II can be distinguished as well as the distributions of Cr III and Cu III. Information on the axial distribution was used to identify the spectra and for identification of overlapping spectral lines. The overview spectra and some spectral windows recorded with high resolution are presented. Analysis of axial distributions of emitted light, which originates from different ionization states, is presented and discussed.
