摘要

The contribution presents the results of comparative study of typical RMF and AMF contact systems used in vacuum interrupters at typical operation conditions. An AC current pulse with a peak value up to 28 kA and frequency about 50 Hz was used. Electrodes were made of Cu-Cr. In addition to conventional arc current and voltage measurements, various optical diagnostics have been used. The arc dynami...
