Power Transformer Selection Guide — Expert Answers

Q: How to calculate transformer capacity for a factory?

A: Total load (kW) × 1.25 safety factor ÷ power factor. Example: 500kW factory → 500×1.25÷0.8=781kVA → choose 800kVA.

Q: What is the typical lead time for a 2500kVA transformer?

A: 30-45 days for oil-immersed, 20-30 days for dry type. Rush order available (+15% cost, 2 weeks).
