초록
This paper presents a study on the NGR problem for harmonic in distribution systems. Overheating of NGR (Neutral Ground reactor), by neutral current in distribution system, is important cause of transformer breakdown of substation. Countermeasures about zero-sequence component harmonic in neutral line are required.
