WebFor a three-phase generator, the full load current is calculated as I = 1000 × S / (√3 × V). Where, S is the generator rating in kilo-volt-ampere (kVA), and V is the generator rated voltage in volt (V). For a single-phase generator, the full load current is calculated as: I = 1000 × S / V. Try it with this calculator' . WebThe full load current calculator calculates the full load current for 1-phase AC, 3-phase AC and DC loads in kW, kVA or hp. Includes step-by-step equations.

WebDC Kilowatts to Volts Calculation. The formula to calculate voltage (V) in volts is obtained by dividing 1000 times the power (P) in kilowatts by the current (I) in amps. This can be represented as V (V) = 1000 × P (kW) / I (A), where V is measured in volts, P in kilowatts, and I in amps. AC Single Phase Kilowatts to Volts Calculation WebAug 6, 2015 · So rated current is 163A, with a power factor of 0.897 lagging and an efficiency of 96.2%. Code G gives you locked rotor kVA on a per hp basis. Locked rotor kVA will allow you to calculate LRA. Code G = 5.6 … WebApr 8, 2010 · If motors they will draw more current @ 208 than the 240 rating but will still use roughly the same power. You need to figure total VA first and then divide by voltage to calculate the amperage, and factor in the 1.73 if balanced across three phases. I come up with 3200 VA @ 208 volts = 15.4 amps. inappropriate fashion games
