Effect of harmonics on reduction of unbalance in three-phase four wire composite network

The unbalanced current drawn by the composite loads in small-scale industries is mainly due to single-phase loads. Any operation of will cause unbalance and produce distortion non-linear neutral increased voltage at load end reduced an increase linear Industries find it difficult balance control current. To overcome problem, this work aims add a passive network different configurations along with shunt active power filter. A set are considered results discussed paper. L C values designed compensate for required reactive canceling negative zero sequence quantities circuit. This paper also reviewed effect filter RMS
