The generating set lines L1 and L2 are connected to bus-bar A. L2 is supplied from a powerful system and L1 is supplying an important industrial plant. A fault is detected in CB1; preventing the circuit from opening, explain how the voltage at CB1 can be reduced to zero, so that repair can be carried out, without interrupting the supply to the important industrial plant.
