neutral current

The line currents of a three-phase four wire system are square waves with amplitude of 100 A. These three currents are phase shifted by 120° with respect to each other. The rms val...

A three-phase load is connected to a three-phase balanced supply as shown in the figure. If $V_{an} = 100\angle 0^\circ$ V, $V_{bn} = 100\angle -120^\circ$ V and $V_{cn} = 100\angl...

$$230$$ $$V$$ (phase) $$50$$ Hz, three-phase, $$4$$-wire, system has a sequence $$ABC$$. A unity power-factor load of $$4$$ kW is connected between phase A and neutral $$N$$. It is...
