The Value of the Capacitor Size
Not what you're looking for?
An electrical supply company charges its consumers a penalty if their reactive energy consumption (Kvar-hour) exceeds half their true energy consumption (Kilowatt-hour).
Calculate the value of the parallel capacitor required to be installed at the factory to avoid the penalty.
I know that:
Apparent power S = 32594.05
Active power P = 26535.32
Reactive power Q = 18927.46
Using the formula:
C = 1/w [1/Zt * Sin Q - 1/Zt * Cos Q * Tan Q]
I get C = 0.000181
How do I get P or S from the following:
The supply is 240 Volts ac at 50Hz.
The total load impedance is Zt = 3.04 at 35.5 degrees.
The power factor is 0.81.
