The IEEE 605-2008 standard provides guidance on the design of bus arrangements in substations to ensure safe and reliable operation of the substation and the power system. The guide covers both rigid bus and strain (cable) bus designs for outdoor and indoor, air-insulated, alternating current substations.

The standard includes information on the advantages and disadvantages of different bus arrangements and provides guidance on the selection of bus types and their construction. It also provides calculation tools to determine the bus size, forces acting on the bus structure, number of mounting structures required, and hardware requirements.

The scope of the standard includes considerations for ampacity, radio influence, vibration, and electromechanical forces resulting from gravity, wind, fault current, and thermal expansion. However, it does not cover electrical criteria for insulator selection, seismic forces, design of mounting structures, considerations for contaminated environments, installation methods, or the design of direct current buses.

The purpose of the standard is to integrate electrical, mechanical, and structural considerations into one document for the design of substation rigid and strain bus structures. Special considerations are given to fault current force calculations, taking into account factors such as decrement of fault current, flexibility of supports, and natural frequency of the bus. These factors are mentioned in ANSI C37.32-1996 but are not included in the equations presented in that standard. The standard aims to provide intended users with the necessary guidance and benefits to ensure a proper bus design.
