摘要

Characteristics of stem play an important role in the leader inception and development, and deserve comprehensive studies. In order to observe the stem experimentally, a schlieren system was established. Experiments in a 1m cone-plane gap under positive impulse voltage were carried out and the discharge current and schlieren photographs of discharge process were recorded synchronously with associated analysis. Experimental results showed that the number of stems were always more than one at the initial stage of the discharge in long gaps. Only 3% of the cases had one stem in our experiments. The number of stems followed a normal distribution with mean 4.01 and standard deviation 1.26. The first corona charge did not have a significant impact on the number of the stems. These stems were concentrated near the cone tip in the range -4 to 4 pixel. Using the method for the position of the stems described in this paper, the distribution of the stems followed a normal distribution with an average of -0.44 and standard deviation 4.31.
