For star connection,
The three-phase voltages are equal but have a phase difference of 120°
between them.
Current through the neutral wire, I is
N
Example 4.4 A three-phase load has a resistance and reactance of 6 W each
for all the three phases. The load is connected in star. A 400 V, 50 Hz, three-
phase supply is connected across the load. Calculate phase voltage, phase
current, power factor, power consumed per phase, and the total power
consumed by the load.
Solution:
