WebThree Phase Amps to kVA Calculation. Calculating Three Phase kVA from Amps formula kVA = Amps x Volts x 1.732 / 1000 Example: So if Amps = 25 and volts = 400 then 25 x 400 x 1.732 / 1000 = 17.32 kVA. Three …
WebTo calculate the kVA we need to know at least the line-to-line voltage (V) requirement of the load and the maximum load phase current (I). For a single-phase transformer, kVA = (V x I) /1000. For a Three-phase transformer, kVA = (√3 x V x I) /1000 = (1.732 x V x I) /1000. Are you struggling to calculate amperage of your load? WebJan 6, 2024 · You can calculate the line current of a transformer by using the appropriate formula for single-phase or 3-phase systems: Single-phase: I = VA ÷ E. 3-phase: I = VA ÷ (E × 1.732) Overcurrent protection. …
