This paper presents an improvement of power factor on inductive loads in Nigeria machine tool plant. Due to the fact that most of the electrical loads are inductive in nature and to provide reduction in distribution losses and the electricity bill charges, a form of power factor correction device is employed, usually in the form of capacitors, which draws leading reactive current to neutralize as much of the lagging reactive component of load current as possible. To improve the power factor in machine tools industries, it is required to install capacitors of appropriates ratings as near to the load as possible. This paper presents a case of an induction machine in a factory having a power factor of 0.75 and has capacity of improving its power factor to 0.928 by connecting suitable capacitors in parallel with the inductions motors.
