Microcontroller › 8051 › any one can find power factor for AC load using 8051 microcontroller › To find Power factor, you
To find Power factor, you should first conver the sine wave into square wave. Take voltage and current referances from PT and CT. Then convert it into square wave. You can calculate the time difference between two waves by turning ON the timmer when voltage pulse goes to high and stop timmer when current pulse goes high. The time difference give you the powerfactor data.
