Dead-tank breakers without need of additional capacitors
Line-to-ground capacitors are used to alter transient recovery voltages and allow circuit breakers to interrupt fault currents. Eliminating them enables substation design to be simplified, maintenance to be reduced, and overall substation costs to be cut.
