As we know it is impractical to connect multiple conductors at one point. Hence we use bus bars, where these connections can be done spaciously and conveniently. So let’s start with different bus-bar schemes or systems in an electrical substation.
The following are the important bus-bar arrangements used in sub-stations : (i) Single bus-bar system: As the name suggests, it consists of a single bus-bar and all the incoming and outgoing lines are connected to it. The chief advantages of this type of arrangement are low initial cost, less maintenance and simple operation.
Each bus-bar has the capacity to take up the entire sub-station load. The incoming and outgoing lines can be connected to either bus-bar with the help of a bus-bar coupler which consists of a circuit breaker and isolators. Ordinarily, the incoming and outgoing lines remain connected to the main bus-bar.
(iii) Duplicate bus-bar system: This system consists of two bus-bars, a “main” bus-bar and a “spare” bus-bar. Each bus-bar has the capacity to take up the entire sub-station load. The incoming and outgoing lines can be connected to either bus-bar with the help of a bus-bar coupler which consists of a circuit breaker and isolators.
The indoor 11kV sub-stations often use single Busbar Arrangements in Substations. Fig. 25.5 shows single Busbar Arrangements in Substations. There are two 11 kV incoming lines connected to the bus-bar through circuit breakers and isolators.
It is easy to see that each bus-section behaves as a separate bus-bar. (iii) Duplicate bus-bar system: This system consists of two bus-bars, a “main” bus-bar and a “spare” bus-bar. Each bus-bar has the capacity to take up the entire sub-station load.
Double bus bar configuration: Another popular configuration is double bus bar configuration. This configuration provides multiple options to connect the incomers to the feeders together. We …
