Single Line Diagram Data Template (Excel)
Free download · Excel (.xlsx)
Collect data for single line diagrams with this Excel template. One row per equipment item: tag, type (TX/SWB/MCC/DB/VFD/GEN/UPS), rating, voltage, fault level, protection device, incoming source, bus section, cable tag, size, and length. Use with IEC 61082 symbols and IEEE 315 designation standards. Essential for populating SLDs accurately and ensuring all equipment data is captured before drafting begins.

Frequently Asked Questions
What is a single line diagram data template?
A single line diagram (SLD) data template is a spreadsheet for collecting all equipment information needed to draw an accurate SLD. It captures equipment tags, types, ratings, voltages, fault levels, protection devices, and cable details in a structured format per IEC 61082 and IEEE 315 conventions.
What data should be collected for a single line diagram?
Key fields include equipment tag, type (transformer/switchboard/MCC/distribution board/VFD/generator/UPS), rating, voltage, fault level at each bus, protection device type and rating, incoming source, bus section identifier, and cable tag, size, and length for each connection.
What is the difference between IEC 61082 and IEEE 315?
IEC 61082 defines documentation standards for electrotechnical projects including SLD layout rules. IEEE 315 (ANSI Y32.2) defines graphical symbols for electrical diagrams. Together they provide the symbol and layout conventions for drawing standardised single line diagrams.
