Single Line Diagram
The first step in preparing a critical response plan. Become familiar with the electrical distribution system layout and design. If you have, a new or existing facility the single-line diagram is vital for all testing.
Servicing and maintenance activities measured against the single-line diagram. The diagram is like a balance sheet as it shows you a snapshot of the facility. The diagram must change when the facility changes. This ensures that your facility is properly protected.
The single-line diagram is your blueprint for electrical system analysis.
An effective single-line diagram will show how the main components of the electrical system are connected.
A typical single-line diagram showing the Red boxes represent circuit breakers. Grey lines represent three-phase bus and interconnecting conductors. Orange circle represents an electric generator. Green spiral is an inductor. Three overlapping blue circles represent a double-wound transformer with a tertiary winding.
In some facilities, changes are added or removed in small increments. Because of this, some part of the system becomes overloaded. Many times circuits are included without appropriate modifications of the single-line diagram.
The single-line diagram provides the map. To enable the proper design of equipment, redundancy, and protection.
To meet these requirements. We can conduct a comprehensive site survey. To develop single-line diagrams for you. Making sure that your facility is to update with any existing diagrams. The includes:
- Listing of inventory equipment
- Verify existence of drawings and that they are available
- Confirm loads are connected to their relevant feeders
- Verify potential failures
- Report the findings and recommended actions
- Update customer-provided single-line drawings.
- Provide a copy of single-line electrical diagram in AutoCAD format
