Now a days Electrical load demand increases rapidly in all area of domestic network, supplied by three wire
and single neutral conductor to each load and forming a three phase four wire (3P4W) system. In that electrical
atmosphere each load having unbalancing condition, which causes the situation of non-linear characteristics in neutral
conductor carrying neutral current due to use of various switching power electronics devices in day to day life, which
harms the neutral conductor and causes defect on loading of distribution transformer while consider the safety and
reliability of the consumers. Various methods have been surveyed in literature to overcome this problem. This review
paper carried out a comprehensive survey of neutral current compensation methods and their technical and economical
limitations. Simulations analysis carried out for single phase shunt active power filter in MATLAB environment in this
paper.
