A balanced three-phase system, with line voltage of 220V/60Hz, feeds a star-connected balanced three-phase load with apparent power of 3kVA and leading 0.8 power factor.

Question

Considering the information presented, analyze the following statements.

I. The current per phase in the load is 5A.

II. The active power of the load is 1800W.

III. The reactive power of the load is 2400VAr.

IV. The power factor of the source can be unity when appropriate values of capacitances are added in parallel with the load.

V. The current at the load is in phase with the line voltage.

VI. The current at the neutral is equal to 14.17A.

VII. An electric stove is a typical example of this type of load.
