Power factor (PF) is one of the most important but often misunderstood quantities of AC power. Both arguments are required and are not optional. Reddit. Edit a Formula. For the purely resistive circuit, the power factor is 1 (perfect), because the reactive power equals zero. The POWER function works like an exponent in a standard math equation. The power factor calculation can be done using a power triangle, the cosine of the angle between active power and apparent power is considered as power factor and it is same as the angle between supply voltage and load current. In excel, if we want to calculate the gravitational force, we will be again using the POWER in Excel that can operate over big numeric values. The power factor calculation does not distinguish between leading and lagging power factors. In reality, PF is a property of the load downstream of the electric source, rather than a property of the source itself. In order to calculate power factor correction for your installation, your should follow the steps below: Step 1 – Calculate Actual Load (kW) (Load) Power kW = Volts V x √3 x Current I x Power factor Pf Step 2 – Calculate Required Power Factor Correction (kVAr) Here, FV is the future value, PV is the present value, r is the annual return, and n is the number of years. The cube root of a number can be calculated manually with the exponentiation operator (^) or with the POWER function. Here, the power triangle would look like a horizontal line, because the opposite (reactive power) side would have zero length. So, we’ll do our calculations to improve the power factor of this motor. Power in Excel takes both the argument as a numeric value; hence the arguments passed are of integer type where Number is the base number, and the Power is the exponent. Chris's Workbench 190 views.
