The metallic vapor density in vacuum arc in a vacuum interrupter is crucial for deeper understanding of the anodic activities and dielectric recovery process. In this work, the objective is to measure the Cr metallic vapor density and its axial distribution along the gap in the vacuum arc between chromium contacts. The method of the optical absorption spectroscopy (OAS) using a broadband light source...
Vacuum circuit breakers are extending their applications from low/medium voltage level to high voltage level due to their good properties. Multi-break vacuum circuit breakers are used in special applications because thry have better breaking capability and withstand higher breakdown voltage compared with single-break vacuum circuit breakers. The objective of this paper is to investigate the reignition...
