Abstract

A discharge on the surface of organic glass in transformer oil was investigated in a nonuniform field at oblique-angled pulses of both polarities with the duration of t equals 3 divided by 300 mu s. The distance between the electrodes was 70 mm. It was found that the dependence U (of spark-over voltage) equals f(t) is characterized by the presence of a minimum in the region 60 divided by 90 mu s. It was established by means of electron-optical investigation that the anomalous progress of the above dependence U equals f(t) is determined mainly by ionization processes preceding the development of the leader channel.
