Harmonic Analysis and Power Factor Correction For Food Processing Industry

Harmonic analysis of the distribution system is essential to study the behavior of equipments connected in the non-sinusoidal system environment for designing and optimal location of filters. Harmonic distortion can have a significant impact on industrial customers such as additional losses and heating of certain network equipment, faulty operation of control equipment and interference in neighboring telecommunication system. In this case study harmonic analysis of food processing industry has done using harmonic analyzer ‘YOKOGAVA’. The aim of the study was to improve the power factor, maintain harmonic distortion within acceptable levels and reduce possible resonance problem at the plant. Analysis of voltage and current harmonics is performed at distribution side point of common coupling before and after connecting APFC panel.
