Design a visual representation of a primary substation. Focus on including essential equipment typically found in a primary substation, such as transformers, circuit breakers, and busbars. Arrange the equipment in a single line or in a compact layout to ensure clarity and easy observation. Ensure that each piece of equipment is clearly labeled or identifiable to aid in understanding. Consider incorporating additional elements such as fences, access roads, and environmental surroundings to provide context for the substation's location and function. --s 250
