Introduction
The Electrical Substation and Switchyard Design course focuses on fundamental safety standards and practices in designing substations and switchyards. An electrical substation is a key component in a power system, responsible for transforming voltages for transmission, distribution, and switching of power. A switchyard operates at a single voltage level without transformers. Understanding and designing these components are crucial for modern power systems. This program covers essential aspects, including electrical, chemical, and personal safety threats in environments containing substations and switchyards.
