For Design Engineers:

  • Fault current calculation: Use Chapter 2's formulas to determine prospective short-circuit current (Ipk and Ik) at the switchgear busbar.
  • Busbar sizing: Refer to the ampacity tables for copper and aluminum to avoid thermal derating.
  • Selectivity analysis: Use the time-current characteristic curves in Chapter 7 to ensure downstream faults don't trip the main breaker.

C. Instrument Transformers

  • Current Transformers (CTs): Transformation ratios, accuracy classes, burden, and saturation effects.
  • Voltage Transformers (VTs): Inductive vs. capacitive voltage transformers, ferro-resonance issues.

A. Circuit-Breakers

  • Operating Principles: Explanation of arc quenching mechanisms.
  • Technologies:
    • Vacuum Circuit-Breakers (VCB): The dominant technology for MV applications.
    • SF6 (Sulfur Hexafluoride) Circuit-Breakers: Usage in HV and specific MV applications (including discussion on SF6 alternatives/sustainability).
    • Air-Blast and Oil Circuit-Breakers: Historical context and legacy maintenance.
  • Operating Mechanisms: Spring-charged, magnetic, and hydraulic mechanisms.
