Field and ion interactions of hybrid AC/DC transmission lines

With the increasing use of DC transmission in existing AC networks, the possibility of AC and DC circuits running parallel to each other and sharing the same right-of-way or even the same tower is increasing. It is important from the point of view of design of such hybrid AC/DC transmission lines to determine the nature and extent of field and ion interactions. A method is proposed to analyze such interactions and is applied to some typical practical hybrid line configurations. >
