A substation with double-busbar configuration employs two sets of busbars. Each power source and each outgoing line is connected to both busbars via one circuit breaker and two disconnectors, allowing either busbar to serve as the working or standby busbar. This setup offers higher reliability and flexibility. The two busbars are interconnected. Eaton's Power Xpert UX system in double busbar configuration is designed for your most critical applications up to 24kV and delivers increased flexibility, reliability and safety. The configuration in back-to-back or front-to-front completes the extensive range of panel types and options available. Learning about the functions of double busbars. Description Three-phase power with currents of up to 5 Amps per phase can be carried, measured and switched by means of the double busbar model. This article explores the concepts, configurations, and applications of both. Compared to double busbar switchgear, single busbar switchgear is definitely easier to use, readily understood by operators, requires less space, and the total cost of installation is less (equipment, site procedures, maintenance, spares holding and space).
