- In the industrial sector the various motoring loads are continuously running and increasing the inductive load. So the power factor in this system get reduces due to the inductive reactive power. But the electricity board has a standard limit regarding the power factor values and if the power factor goes below the specified limit the electricity company charges the penalty to the industrial consumers. APFC device reads power factor from line voltage and line current by determining the delay in the arrival of the current signal with respect to voltage signal from the function generator with high accuracy by using an internal timer. This time values are the calibrated as phase angle and corresponding power factor. Then the values are displayed in Liquid crystal display modules. Then the motherboard calculates the compensation requirement and accordingly switches on different capacitor banks. This is developed by using AVR microcontroller.
