4. 1500 kVA Transformer Amps Explanation
The rated current of the 1500 kVA transformer (1500 kVA transformer amps) can be calculated as follows:
-
Low-voltage side (480Y/277V) = 1500 × 1000 ÷ (√3 × 480) ≈ 1804 A
-
High-voltage side (13.8kV) = 1500 × 1000 ÷ (√3 × 13,800) ≈ 62.8 A
The high-voltage current varies slightly depending on the input voltage (13.2kV, 24.9kV, 34.5kV). Accurate calculations ensure system safety and reliable operation.
