Analysis of the Breakdown and Electrical Arc in the Process of Switching on

Abstract

AbstractSwitching on current in an electric circuit occurs hence not due to securing the contact of contacts, but as a result of electric break down of the isolation of the given environment. The switching-on arc glowing time depends hence on the value of the intensity of electric field in the contact area, and on the velocity of contacts closing. The paper describes the analysis of the electrical fields and problems of the arc switching time in contact switches during making of a current in current paths and test.
