This PDF is a practical compilation of the most common electrical design calculations—think load estimation, voltage drop, cable sizing, short-circuit analysis, power factor correction, lighting calculations (lumen method), and basic feeder/protection device coordination. Three-phase current: I = 1000 × kVA /

15. Appendix: Useful formulas (compact)

• Three-phase current: I = 1000 × kVA / (√3 × V_L-L)
• Single-phase current: I = 1000 × kVA / V
• kW ↔ kVA: kVA = kW / pf
• Voltage drop (three-phase): Vd = √3 × I × (R cosφ + X sinφ) × L
• Transformer per-unit ISC: ISC ≈ (Transformer kVA) / (V × (%Z/100)) × constant (use exact standard formula)
