Course Outline

Fault analysis and calculations

  • Per-unit representation
  • Balanced faults – generator equations, Thevenin equivalent circuit, fault on radial line, fault on looped system
  • Symmetrical components. Sequence networks – transmission line, generators, transformers, radial system, looped system
  • Fault analysis using symmetrical components

Industrial power system protection concepts

  • Industrial power system topology – radial system, looped system
  • Industrial system grounding – ungrounded, solidly grounded, low-impedance, high-resistance grounding
