Generator Set Motor Starting MacAllister Power Systems
Motors, either loaded or unloaded, draw several times rated full load current when starting. This is termed locked rotor current or starting kVA (SkVA). SkVA is calculated from locked rotor current like this: SkVA = V x A x 1.732 / 1000. In-rush current to the motor causes a rapid drop of generator output voltage. In most cases, a 30 percent voltage dip is acceptable, depending on the equipment you already have on
