Transformer rating: 75 kVA: Number of shifts loaded: 1 (8760 h/y) Energy cost: $0.070/kWh: The Total 15-Year Operating Cost is calculated: Operating Cost (in $) = [(NLL x 8760 x 0.070) + (FLL x 8760 x 0.070)] x 15

a 75-kilovolt-ampere (kVA), three-phase transformer with an input voltage of 480V will be installed in a small industrial plant. This transformer is rated 75,000 VA (75 kVA × 1,000 = 75,000). The primary side current will be 90 amperes (A) (75,000 ÷ 480 ÷ 1.732 = 90.2 = 90).
