(11)(D)1UITDITOQ.382.3 My These the course(B) 100The line currents of a three-phase four wire system are square waves with amplitude of 100A. These three currents are phase shifted by 120° with respect to each other. The rms valueof neutral current is(A) O A(C) 100 A(D) 300 A

Answer»

Line current are always 120° apartsoas we knowVrms= Vo/√2here due to square waveand 3- phase as well100/√3
