Arc Flash Studies. The Arc Flash Blog The arc flash blog is designed to help facility managers and maintenance professionals understand and mitigate the risk of electric arc flash. Need a site single-line diagram? Wondering how to draw a circuit diagram?

Then this article is for you! What is a schematic diagram? Why do you need it? How to draw a circuit diagram? Which electrical symbols do you use? What info do you need to include? What is a single line diagram? Why do I need a single-line diagram? There are two main reasons you need it: For everyday operations and maintenance , as well as engineering power system studies. Power system studies Having an up-to-date SLD is required to complete a power system study.

A main program shall include the continual upkeep and review of the following power system studies and drawings: One-line diagrams; Short-circuit studies; Coordination study; Arc flash incident energy study; and Load flow study. A significant change could be: A new installation or system modification, Change in utility or source Change in system impedance, configuration, or loading, Change in protection devices or settings.

How to draw electrical single line diagrams. Wiring diagram symbols To start you should know what symbols to use to represent your equipment. Incoming voltage Fault level and impedance optional. Rated Amperage. Rated Amperage Model. Rated amperage Model Trip settings optional. Rated amperage Model. Power HP. Turns ratio. Function number Instrumentation connection.

Electrical one line diagram design. Connect the schematic symbols To start, connect your electrical symbols using one line. Indicate equipment separation You can also group symbols using a dash-dotted box to indicate they are part of one piece of equipment.

Add equipment data Once you have all the symbols and connections figured out you can start adding the equipment info. Electrical equipment information. The most important information to include is: Incoming service voltage Equipment rated current Identification names of equipment Bus voltage, frequency, phases, and short circuit current withstand ratings Cable sizes, of cables, and lengths Transformer connection type, kVA, voltages, and impedance Generator voltage and kW Motor HP Current and Voltage ratios of instrument transformers Relay device numbers Looking at our diagram again we can separate the info into voltage , amperage , and impedance to make sense of what is included for each piece of equipment.

Voltage The incoming voltage is Architects and building owners will appreciate the simplicity of the diagram, which will provide an overall description of the system on a single sheet of paper. Best Architecture Books Our list of the top reference books for architects - these are the ones we have on our shelf. Electrical One-Line Diagram.
