Ensure the primary and secondary connections match your system topology. Rating Tab: Input the primary kV and secondary kV (e.g., ). Enter the power rating in MVA or kVA.
Instead of guessing values, click the Typical Z & X/R button. ETAP will automatically populate standard IEEE/IEC values based on the transformer's size and voltage class. etap tutorial
[ Power Grid ] | (Bus 1) 13.8 kV | [Y-Y Transformer] (Step-Down) | (Bus 2) 4.16 kV / \ / \ [Induction Motor] [Lumped Load] Execution Steps Ensure the primary and secondary connections match your
Name your project and select your preferred (English or Metric). Set the Frequency (50Hz or 60Hz) based on your region. 2. Build the One-Line Diagram Instead of guessing values, click the Typical Z & X/R button
Click the "Run" button. The software will show the short-circuit current (kA) at the faulted bus. 6. ETAP 2026 Best Practices and Resources
The accuracy of your simulation depends entirely on the accuracy of your input data.
Connect a transformer to step down the high voltage to a usable distribution or utilization level.
