The arrangement provides the less flexibility and hence used in the small substation where continuity of supply is not essential.The only disadvantage of such type of arrangement is that the complete supply is disturbed on the occurrence of the fault.The advantages of single bus bar arrangements are All the substation equipment like the transformer, generator, the feeder is connected to this bus bar only. The system has only one bus bar along with the switch. The arrangement of such type of system is very simple and easy. The different type of electrical busbar arrangement is shown in the figure below. But in a large substation, the additional busbar is used in the system so that the interruption does not occur in their supply. The small substation where continuity of the supply is not essential uses the single bus bar.

The installation of the bus bar is cheap.The maintenance of the system did not affect their continuity.The bus bar arrangement is simple and easy in maintenance.The following are the electrical considerations governing the selection of any one particular arrangement. The selection of the bus bar is depended on the different factor likes reliability, flexibility, cost etc. The various types of busbar arrangement are used in the power system.

The copper and aluminium are used for the manufacturing of the electrical bus bar. The rectangular bus bar is mostly used in the power system. The electrical bus bar is available in rectangular, cross-sectional, round and many other shapes. On the occurrence of a fault, the circuit breaker is tripped off and the faulty section of the busbar is easily disconnected from the circuit. The bus bar system consists the isolator and the circuit breaker.
