title = "Preliminary spectroscopic investigation of HVCB contacts erosion",
abstract = "Spectral emissions from arcs in air between electrodes used in high-voltage circuit breakers (HVCBs) have been investigated at AC currents up to 32kA peak. Time-resolved average temperature and copper atoms concentration have been derived from the arc spectra. The copper vapor mass deduced from these measurements was used to estimate the electrode erosion rate which was compared with directly meas-ured material loss. High speed photographs of the arc were taken to provide further electrode erosion in-formation. The results indicate the possibility of using the approach for online monitoring of in-service HCVBs.",
