This paper presents a harmonic filter design to minimise harmonic distortion in a factory. In an applicational example, the power transformer feeds a rotary mill, which is driven by semiconductor devices and is generating harmonics in the power system. Experimental harmonic measurements have been recorded by using a power and harmonic measurement device. By using the recorded data, a single tuned passive filter has been designed to reduce the fifth harmonic component caused by the power converter which drives an induction motor in the factory. The solutions recommended in this paper can be used to increase power factor and to reduce harmonics for improving the power quality and the plant productivity.
