  • HV And MV Switch Disconnectors And Isolators in Power System

    Switch-disconnectors are nowadays used only in MV installations, most commonly in MV switchgears and in MV overhead lines (see Figure 1) and they have usually an arcing chamber (air or SF6 insulated) to extinguish the arc, but they also perform that extinction in the air (Air Break Switch – ABS).
