Power Factor Using Two Wattmeter Calculator

Power Factor Using Two Wattmeter Calculator

Calculate the power factor of a balanced three-phase system using the two-wattmeter method.

Using the formulas:
\[ \tan\phi = 1.732\,\frac{W_1 – W_2}{W_1 + W_2} \] and \[ \text{PF} = \cos\phi \]

Step 1: Enter Wattmeter Readings

Example: 5000 W

Example: 3000 W

Formulas:
\( \tan\phi = 1.732\,\dfrac{W_1 – W_2}{W_1 + W_2} \)
\( \text{PF} = \cos\phi \)
