![]() You can easily remove selected objects using the Delete icon in the toolbar. To move objects, first select them, then drag them to their new location. Double-click on the text to get enhanced text options in the Format panel. Text size, font and colour can be altered in the Text tab of the format panel. Edit the style of the shape (Rounded, Shadow, Glass, Sketch).Change the width, colour and style of the line or remove it.You can edit shapes in the format panel on the right. You can add/remove/copy shapes, lines, edit texts and details as per your requirements. Please note: The information that is not entered in your project will appear as "NOT SPECIFIED" in the template. System Specifications in the template are auto-populated as per your design. This will generate the diagram for your project as per your country. Click on "Apply" after selecting the panel system and template.The template will default to Org country (AU or UK), but if you want to design a project in another country, you can select the available templates from the second dropdown menu.Select the panel system from the dropdown if you have multiple system options. ![]() After saving your project you can click on ' SLD' from the header: Once you complete your design, make sure you save the project.You will need a design with relevant components and stringing to generate the fully populated template. ![]() Single Line Diagrams or Schematic Diagrams on OpenSolar take information from the design of your project. How can you generate the Diagram on OpenSolar? Generally it is used to communicate with an installer how the system will be connected. It can also give key information on installation details including voltage and current of stringing in the system. What is a Single Line/Schematic Diagram ?Ī Single Line Diagram (SLD) (also know as Schematic Diagrams) is a simplified representation of the components in an electrical system and denotes how the components are laid out. Please note that Single Line Diagrams are currently available in AU and UK (Schematic Diagram) only. Another box represents the power control center, motor control centers and connecting them with feeders.Ĭurrent transformers are shown in two places with indicators.Ī neutral ground resistor (NGR) is shown connected to a neutral line to provide protection to the generator against earth faults.Ĭircuit breakers are shown at various places for isolation of power for the transformer, PCC, and MCC.This article will walk you through how to generate and customise SLD's on OpenSolar. The single line diagram is divided into two portions, from generation to substation are shown in a dotted grey line box. Greyline represents three-phase power in a single conductor. The blue circle overlapped represents the transformer from HT to LT power. The red box represents the circuit breakers. From the above one-line drawing, one can easily understand that the line shown from power generation, number breakers, HT/LT transformer, power control Center (PCC), then Motor control center, finally to feeders. The above single line diagram shows right from generation to distribution stage. The restoration of power can be possible by identifying.Įlectrical engineers: Use single line diagrams to understand system behavior and to make changes to the power system to improve performance.Įnd-users: Use the single-line diagrams to identify their electrical equipment, circuits, and protection apparatus.įamiliarity with electrical symbols helps one to understand the overall system connections. System operators: Use the single-line diagrams to identify the electrical placement of breakers, switches, transformers, regulators, and so on in substations that may indicate alarms. It shows how all alternate sources may be isolated. Line crew: Single line diagram drawing tells the worker at a glance where the disconnecting means is located.
