Abstract

Abstract Vacuum circuit breakers (VCB) are now widely used for switching of electric arc furnaces. However, the associated switching transients have raised many concerns and have led to failures in industrial power systems. High frequency current and voltage transients result due to prestrike phenomena during the VCB energization. This paper presents a detailed switching case study of an arc furnace VCB in a steel melting plant. The VCB prestrike phenamenon is simulated and studied using the electromagnetic transient programme. The simulation model is verified by on- site measurements. The ground potential rise during the switching process is thoroughly investigated in order to analyse the practical methods to mitigate the switching transients. Additionally, some practical aspects of physical design and installation are discussed.
