Description of Power Analysis in AC Circuits
This online AC Circuit Analysis training gives you a step-by-step understanding of how voltage, current and phase relationships determine real and reactive power in practical systems. You’ll connect core theory to hands-on tasks such as power triangles, complex power, and power factor correction with capacitor banks. The programme culminates in three-phase power methods used in industry.
Each module provides actionable worked ideas so you can analyse loads, reduce wasted energy and communicate clearly with maintenance teams or clients. Designed for beginners and developing professionals, the course focuses on simple frameworks, clean maths and repeatable procedures that reduce errors in day-to-day AC power work.
Curriculum Overview of AC Circuit Analysis Course :
Introduction — Get a clear roadmap for the course and how AC power analysis connects to energy bills, equipment sizing and compliance. Align expectations, tools and notation for consistent calculations.
Power & Energy Defined — Build precise definitions for instantaneous/average power, RMS, real PP, reactive QQ and apparent SS. Learn how meters and tariffs reflect these quantities.
Power in Reactive Circuits (Part A) — Examine phase shift in inductive/capacitive elements. Use phasors to relate voltage/current and set up the power triangle.
Power in Reactive Circuits (Part B) — Extend to mixed R-L-C networks. Interpret lead/lag behaviour, sign conventions for QQ and typical plant scenarios.
Power Trig Identities — Apply identities (cos φ, sin φ, tan φ) to link power factor, impedance angles and component values. Convert between triangle legs and circuit parameters.
Power: Real and Reactive — Work end-to-end examples converting measured V, I and φ into PP, QQ, SS with units (W, var, VA). Communicate findings with neat report templates.
More on Average, Real & Reactive — Handle non-ideal waveforms and averaging. Tackle measurement pitfalls and set tolerances for shop-floor checks.
Power – Complex Power — Use S=P+jQS=P+jQ in phasor form; switch between rectangular and polar. Tie complex power to meter readings and equipment nameplates.
Power Factor Correction — Size capacitors to shift φ toward unity, estimate kvar needed, and verify with post-install PF checks. Avoid over-correction and resonance traps.
Power in 3-Phase Circuits — Compute three-phase power P=3VIcosφP=\sqrt{3}VI\cos φ for balanced loads, line vs phase values, and common wiring (Y/Δ) considerations.
