Transformer Sizing Calculator helps contractors and tradespeople accurately size, spec, and estimate materials and systems.
Rumus
kVA = (Volts × Amps) / 1000 for single-phase; ×1.732 for three-phase
Panduan Langkah demi Langkah
- 1Calculate load kVA, add 20% safety margin for transformer sizing
- 2Apply the formula using your project measurements
- 3Add required safety factors or waste allowances per code
Contoh Terpecahkan
Masukan
480V, 100A, three-phase
Hasil
kVA = (480×100×1.732)/1000 = 83.1 → use 100 kVA
Kesalahan Umum yang Harus Dihindari
- ✕Not applying code-required safety factors or derating
- ✕Forgetting to account for waste and cut losses in material estimates
