Module timeline

  1. One-line diagrams for analysis

    Guided scenario 30 min

    Build a one-line carrying the ratings, impedances, and settings a study consumes.

    Lab: One-Line Diagram Builder & ExplorerCompletes on: lab opened, guided scenario steps confirmed, knowledge check submitted, reflection confirmed
    Open module

  2. Available fault current

    Guided scenario 40 min

    Estimate available fault current and identify which inputs move it most.

    Lab: Fault Current & Short-Circuit SimulatorCompletes on: prediction recorded, lab opened, guided scenario steps confirmed, knowledge check submitted, reflection confirmed
    Open module

  3. Symmetrical components and sequence networks

    Guided scenario 45 min

    Decompose an unbalanced condition into sequence components and interpret each network's meaning.

    Lab: Symmetrical Components & Fault VisualizerCompletes on: prediction recorded, lab opened, guided scenario steps confirmed, knowledge check submitted, reflection confirmed
    Open module

  4. Substation bus arrangements

    Guided scenario 30 min

    Compare bus arrangements on reliability, maintainability, and cost.

    Lab: Substation & Switchgear Bus Configuration ExplorerCompletes on: lab opened, guided scenario steps confirmed, knowledge check submitted, reflection confirmed
    Open module

What you will be able to do

  • Build a one-line that carries the data a fault study needs
  • Estimate available fault current and identify what drives it
  • Decompose an unbalanced fault into positive, negative, and zero sequence components
  • Compare substation bus arrangements on reliability and maintainability

Prerequisites

  • Electrical Foundations
  • Comfort with per-unit reasoning and complex quantities

What counts as complete

All four modules marked complete. Symmetrical components sits here, not in Foundations, because it assumes phasor algebra and fault analysis.

Opening a lab never marks a module complete on its own.
