Hello,

 

What you mentioned it is not exactally correct, as kWh is energy , so  as you mentioned :

“Now the formula,which you know, KWH = Line Current * Line Voltage * Power factor can be applied.

The only unknown value ‘current’ can be calculated.”

 

You must not use de time, as P= dW/dt, the correct is kW = Line Current * 1,73*Line Voltage * Power factor * efficiency.
