Modern vacuum direct current circuit-breakers operate on the principle of breaking current with counter-current. If they are used in power systems of electric traction, good switching durability and excellent protection of receivers can be obtained, thanks to the strong limitation of short-circuit current. However, in such a case high durability of varistor operating together with the switch, limiting switching overvoltages that occur during switching operation is required. In order to reduce the energy emitted in varistors in extreme conditions and thus to prolong varistor live, additional supporting circuit can be used. Research is being conduced on chosen configurations of such system.
