  • How to divide the main busbars

    How to divide the main busbars

    The main bus splits into L1, 2, and 3 busses, and each further divides into an additional three bars. Below is a complete breakdown of every major type of busbar arrangement — from the simplest single busbar scheme to advanced configurations used in high-voltage transmission substations. Designing a substation involves not only the visible equipment and ratings but also the less apparent factors—operational. When a number of generators or feeders operating at the same voltage have to be directly connected electrically, bus-bars are used as the common electrical component. It is the simplest and cheapest scheme. Its limitation is that maintenance of bus and/or circuit breakers cannot be carried out. In Simple words, a bus-bar is a common connection point or a node for multiple incoming and outgoing circuits such as power lines or feeders. It is an alternative to traditional cabling and provides numerous advantages to the Installer and Client including savings on space, time and cost.
