Answer 1

Answer:

y connection, voltage applied across each impedance=4/3 so phase current = v/z=400 /10 /3 amps power

Answer 2

Answer:

The line current is 5.217 amperes.

Explanation:

In a three phase balanced system of star connection, the total power consumed is $P=\sqrt{3}V_LI_Lcos\alpha$ where $cos\alpha$ is the power factor, $V_L$ is the line voltage and $I_L$ is the line current.

Between a three-phase source and load, the current through any one line is called the line current.

It is asked to find the line current of the three phase 415V, 50 HZ supply for the balanced load of 3000 watt at 0.8 power factor is connected in star.

The three phase wires are connected to a common point or star point and Neutral is taken from this common point is called as the start connection. It is also called as Y or Wye connection because of its shape.

$P=\sqrt{3}V_LI_Lcos\alpha$

$3000=\sqrt{3} *415*I_L*0.8$

$I_L=\frac{3000}{\sqrt{3} *415*0.8}$

$I_L=5.217$

Therefore, the line current is 5.217 amperes.
