In our system using stpm34, stpm34's registers are read every 5 seconds.
Of course, during those five seconds the load can change.
To calculate the power factor using the stpm34 register values I read, I calculate the "Active Power (ph1_reg5)" / "Apparent RMS Power (ph1_reg8)".
However, depending on the state of the load, power factor greater than 1 may appear.
What is the problem?
Also, is there a way to find the average value of each of Vrms and Irms for 5 seconds?
