Two wattmeters, both have reading of 3 kW when connected for the two-wattmeter method with current coils in lines A and B of a 600 V ABC circuit having a balanced A load. The Δ phase impedance will be
  • a)
    resistive with Zp - 125 Ω,
  • b)
    inductive with Zp - 180 Ω
  • c)
    resistive with Zp = 180 Ω
  • d)
    capacitive with Zp - 200 Ω
Correct answer is option 'C'. Can you explain this answer?

we have
(Since W1 = W2 = 3 kW)
or, cosθ= 1
Hence, the load will be purely resistive.

Phase angle between line A and the voltage is 30 degrees. What is the total power consumed by the load?

Using the two-wattmeter method, the total power consumed by the load can be calculated as:

P_total = W1 + W2

Where W1 and W2 are the readings of the two wattmeters.

In this case, both wattmeters have a reading of 3 kW, so:

P_total = 3 kW + 3 kW
P_total = 6 kW

Therefore, the total power consumed by the load is 6 kW.
