How do you read an overhead distribution line diagram?

2025-08-13

Reading an overhead distribution line diagram involves understanding the standardized symbols and the logical flow of the system.

  1. Follow the Power Flow: Diagrams are typically read from top to bottom, starting with the highest voltage source (like a substation) and moving down to the lowest voltage loads (like a residential transformer).

  2. Identify Components: Each piece of equipment—from switches and circuit breakers to transformers and lightning arresters—is represented by a specific, standardized symbol. A good diagram will include a legend or key to help identify each component.

  3. Note Key Information: Look for annotations and labels on the diagram. These often include voltage ratings (e.g., 33kV), equipment specifications (e.g., kVA rating of a transformer), and conductor details (e.g., ACSR 185mm²).
