ELECTRICAL DIAGRAMS – PART – 04 - SINGLE LINE DIAGRAM (SLD) IMPORTANCE AND APPLICATIONS

SINGLE LINE DIAGRAM
The single-line diagram is the blueprint for electrical power system analysis. It is the first step in preparing a critical response plan and to understand thoroughly familiar with the electrical distribution system layout and design.
IMPORTANCE OF SLD
1. The SLD is the roadmap for all future testing, service and maintenance activities.
2. It provides a picture of the facility at a moment in time.
3. It needs to change as your facility changes to ensure that your systems are adequately protected.
4. The SLD is making the electrical system easily understandable for any technical person inside/outside of the factory.
APPLICATIONS OF SINGLE LINE DIAGRAM
1. Short circuit calculations             2. Coordination studies
3. Load flow studies                        4. Safety evaluation studies
5. Electrical safety procedures         6. Efficient maintenance
