Question
n 3-phase power measurement by two-wattmeter method, the two wattmeters read as W1 = 300 W and W2 = 300 W. Then the load is said to be operating at ________ *Unity power factorLagging power factorZero power factorLeading power facto
Solution
The load is said to be operating at Unity power factor.
Here's why:
In a 3-phase power measurement by the two-wattmeter method, if the two wattmeters read the same (W1 = W2), it indicates that the load is operating at a unity power factor. This is because the power factor is a measure of how effectively electrical power is being converted into useful work output.
A unity power factor (1.0) signifies that the voltage and current are in phase with each other, meaning all the power is being effectively used. In this case, since both wattmeters are reading the same, it indicates that the power is being equally distributed and used, hence a unity power factor.
