Within the background of the technical and scientific co-operation between Electricite de France, the Polytechnical Institute of Bucharest and the Ministry of Electric Energy, Romania, the physical characteristics of impulse corona discharge around conductors have been investigated as well. A great number of experimental tests have been conducted to this purpose. The authors deal with several physical characteristics of corona discharge phenomena around conductors, such as streamer length, length dependence on time, streamer speed (i.e. speed variation with time) and the discharge discrete characteristic.<>
