Physics · Power Systems
In per unit system, the base values of power, voltage, and current in a three-phase system are related by which equation?
- 1Base MVA = (Base kV)2 / Base impedance
- 2Base MVA = Base kV × Base current
- 3Base MVA = 3 × Base kV × Base current
- 4Base MVA = √3 × Base kV × Base current✓
Correct answer
Base MVA = √3 × Base kV × Base current
