Question

3. A 400 V, 3-ph 4 wire star connected system supplies 3 resistive loads of 15 KW, 20 KW and 25 KW in the Red, Yellow and Blue phases respectively. Determine the current flowing in each of the four conductors[1]. 4. Eight Kilo-Watt (8 KW) is found by the two watt-meter method to be the power input to a 3-ph motor. Determine the reading of each watt-meter if the power factor of the system is 0.85 [1]. 5. Three identical coils each of resistance 30 ? and capacitance 60

Step 1

For a star-connected system, the line voltage is equal to the phase voltage. Therefore, the phase voltage is 400 V. The power in each phase is given by P = V*I, where V is the phase voltage and I is the phase current. Therefore, the current in the Red phase is 15 Show more…
