Converting kilovolt-amperes (kVA) to amperes (amps) is essential for understanding electrical systems' current requirements. In single-phase circuits, the current (I) in amps is calculated by multiplying the apparent power (S) in kVA by 1,000 and dividing by the voltage (V) in volts: I(A) = (S(kVA) × 1,000) / V(V). For three-phase circuits, the formula adjusts to account for the system's configuration. When using line-to-line voltage, the current is determined by multiplying the apparent power by 1,000 and dividing by the product of the square root of 3 (approximately 1.732) and the line-to-line voltage: I(A) = (S(kVA) × 1,000) / (√3 × V L-L(V)). Alternatively, with line-to-neutral voltage, the formula becomes: I(A) = (S(kVA) × 1,000) / (3 × V L-N(V)). These calculations are crucial for accurately sizing electrical components and ensuring system safety and efficiency.
