Two different types of buses are used in substations: the rigid bus and the strain (cable). Information is provided by this guide on the different bus arrangements used in substations stating the advantages and disadvantages of each. Information as related to each bus type and construction is also provided. Once the bus type is selected, the calculation tools for each bus type are provided by this guide. Based on these calculations, the bus size, forces acting on the bus structure, the number of mounting structures required, and hardware requirements can be specified by the engineer.
