Substation Design

High voltage substation design is a complex engineering activity that embraces a wide variety of disciplines. This comprehensive overview brings these disciplines together to give you an interactive guide to high voltage, air or gas insulated substation design.

The course considers all aspects of the design process, including a detailed review of network topology, the interaction of the different elements of substation design and operation, an introduction to substation equipment and its function, and an explanation of the many interfaces between engineers, architects and other specialists that are required for substation construction.
