| Outline of Final Research Achievements |
Nitrogen molecule accumulates internal energy easily during a long period by electrical discharge. Accordingly, electrons are supplied continuously even after discharge interruption. Phenomenon of electron supply is very dangerous for the power equipment. Thus, to decrease the number of supplied electrons, small amount of gases which have properties with electron attachment effect or de-excitation effect of internal energy. Results showed that de-excitation gas was not effective. On the other hand electron attachment gas, especially SF6 was effective. From the results it was also deduced that nitrogen atom accumulates internal energy for a long period under the condition of high pressure.
