Abstract:Numerical simulations are commonly used to elucidate the arc phenomenon in electrical railways and analyze its physical property variations. However, the initial conditions of the molten metal bridge must be set to accurately mimic the arc phenomenon. Therefore, the radius and length of the molten metal bridge are experimentally measured immediately before arc generation for four different contact strip materials as the cathode and copper contact wire as the anode. It found that the radius and length of molten… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
