A 3-phase AC transmission line has a total resistance of 10 Ω and a total reactance of 20 Ω. If the load current is 100 A per phase, what is the total power loss in the transmission line?
Q1. A 3-phase AC transmission line has a total resistance of 10 Ω and a total reactance of 20 Ω. If the load current is 100 A per phase, what is the total power loss in the transmission line?
Answer: 4 kW
Explanation: Using the power loss formula, the total power loss is calculated from P_loss = 3 * I^2 * (R + X^2/R), giving 4 kW
