In the case of switching back-to-back capacitor banks, there will be inrush current while closing the circuits which will damage the contact surface of vacuum interrupters (VIs). The objective of this paper is to investigate the characteristics of the prestrike arc under the influence of axial magnetic field with different amplitudes of inrush current. Two groups of VIs with a rated voltage of 12kV...
In the case of back-to-back capacitor banks switching, the inrush current arcs can locally melt the contact surfaces of vacuum interrupters (VIs) during prestrike processes. The contact materials significantly influence the behaviors of the inrush current prestrike arcs. The objective of this paper is to determine the influence of contact materials on inrush current arc behaviors of vacuum interrupters...
