Distribution & power factor

Voltage drop along feeders and capacitor-based PF correction.

Lessons

Lesson 1

Voltage drop on a distribution feeder

ΔV ≈ √3·I·(R cos θ + X sin θ), why leading PF can boost voltage, and how to size conductors for both ampacity and drop.

Sophomore ~10 min
Lesson 2

Power factor correction with capacitor banks

Q_cap = P · (tan θ_old − tan θ_new), bank types, where to install, harmonic resonance, and the simple-payback economics.
