Abstract
Although in recent years, large DC machines have gradually been replaced with variable-speed AC machines, many large DC machines are still operating in steel mills. Flashover is still a frequent occurrence and has been ongoing issues since DC machines were first brought into use. In this investigation, flashover experiments were performed using model tests. The sustained voltage of the DC arc was cleared and copper dragging was found to be related to flashover.
