FIELD: electricity.
SUBSTANCE: invention relates to an electrical bus system comprising first busbar zone (Z1, Z3) and second busbar zone (Z2, Z4), at least one first feeder bay (F11, F12, F13, F14, F3), connected to first busbar zone (Z1, Z3), and at least one second feeder bay (F21, F22, F23, F24, F4), connected to second busbar zone (Z2, Z4), wherein the at least one first feeder bay and the at least one second feeder bay are coupled together by a bus coupling section (BCS3, BCS4, BCS5), wherein a current transformer and two circuit breakers (CT7, OCT7, OCT8) are arranged in the bus coupling section (CB6, CB7, CB8, CB9).
EFFECT: said current transformer in the coupling section has one of said circuit breakers on each of its sides.
