Electrical Substation is a part of an electrical generation, transmission, and distribution system where voltage is transformed from high to low or reverse using transformers. Coursera's Electrical Substation catalogue teaches you about the basic concepts of power transfer, equipment, safety, and maintenance of substations. You'll learn about various types of substations, their components such as transformers, circuit breakers, busbars, and disconnects. Further, you'll also gain insights on substation safety protocols, grounding systems, testing and commissioning procedures, environmental and regulatory standards, and modern developments in substation technology. This knowledge will equip you to contribute effectively in power engineering and utility industries.
