Neutral Current Calculation of Electric Pole in Distribution Line
배전선로 장주의 중성선 전류 계산
Abstract
If the three phases are not balanced, the current in neutral line is not zero. Then, the induced voltage can be generated In communication line. The KEPCO's rule about unbalanced current in single electric pole is a twenty percent of phase current. But the unbalanced current in double electric pole can't decide the rule because there are many different views. This paper develops the calculation and analysis technique of neutral current in single electric pole and double electric pole using equivalent circuit analysis, vector analysis and EMTP simulation.
