This paper represents analysis and study the effects about improve power factor for an electric distribution network in Al- Muthanna governorate, and show method Calculation of power factor, apparent power, reactive power and current, compare these results with regard to before and after the improved power factor in the electric distribution network in Al- Muthanna governorate. This paper represents the results of the improvement of the power factor by increasing the efficiency and the capacity of the electrical system…etc. Calculation of the percentage of the reduction of electric power losses and calculating the monthly cost of this reduction The difference in the apparent power between before and after improvement is 19.5 MVA from the change of power factor in 78 feeders of the electric distribution network of Al- Muthanna Governorate.

Keywords: Power factor, relative power.
