Designing a transmission line with minimum environmental impact requires a study of three factors, namely, the impact of electrical fields, the visual impact of the design and impact of physical location. The Ionic current environment under a DC line is significantly different from that existing under AC lines. Corona on power conductors causes the power loss in high voltage transmission system. Not only the power loss, but it is also responsible for generation of space charge Ions, audible noise, television interface etc. Drifting of these space charge ions towards the ground plane in the direction of electric field causes “Ionic current” flow to any living organism which moving under these line conductors Hence it is very important to study the corona generated ionic current environment of high voltage transmission system. In this project, in order to analyses this corona generated ionic current environment completely, an attempt is made to generate and study the corona generated ionic current flow for different line conductor diameters with DC supply and AC supply. The proposed project work gives the laboratory model experimental setups to generate the corona phenomenon by using “TESLA coil” for different electrode configurations. Also the variations of ionic current flow for different line conductor diameter are presented for DC supply and AC supply.
