<p>The present invention relates to an apparatus for removing a common line current, capable of completely removing the common line current flowing from a load system to a power system which is a zero phase current and an imbalance load current. According to the present invention, the apparatus for removing the common line current includes the power system (10) which has a power common line (10-1), the load system (20) which has a load common line (20-1), a transformer (110) for distributing the common line current, and a transformer (120) for removing the common line current which has a winding ratio K set to control the current flowing from the load common line (20-1) to the power common line (10-1). According to the above configuration, the apparatus for removing the common line current is formed between a phase line and the common line of the load system. The present invention prevents the common line current from flowing in the power system by controlling the winding ratio of the apparatus for removing the common line current.</p> |
