Single Line Diagram (SLD)


Apogee Consultancy to provide Single Line Diagram is a user-friendly interface for creating and managing the network database used for schematic network visualization. The single-line diagram is the blueprint for electrical system analysis. It is the first step in preparing a critical response plan, allowing you to become thoroughly familiar with the electrical transmission system layout and design. The single-line diagram also becomes your lifeline of information when updating or responding to an emergency. An accurate diagram ensures optimum system performance and coordination for all future testing, and can highlight potential risks before a problem occurs.
