With cross-tie disconnector “DT”, the power of line A can be switched to branch A1, bypassing the busbar. The busbars are then accessible for maintenance. Each branch requires only one circuit-breaker, and yet each breaker can be isolated without interrupting the power. In many places, we see the design of a substation with two separate busbars being fed from two different transformers and sharing the load between them. In case of failure of either of the transformers, busbars, cables or their associated switchgear, a changeover option between the two will be at. Yes, a double bus system can be configured with a bypass or a bus tie connection and/or multiple switching arrangements. As we know it is impractical to connect multiple conductors at one point. The result of. The arrangement and connection of incoming and outgoing feeders in grid stations and substations and the number of busbars have a significant influence on the supply reliability of the power system.
