Webthe Townsend–Meek criterion I. Madshavena, O. L. Hestadb, P.-O. Åstranda,∗ aDepartment of Chemistry, NTNU – Norwegian University of Science and Technology, 7491 Trondheim, Norway bSINTEF Energy Research, 7465 Trondheim, Norway Abstract We present a software to simulate the propagation of positive streamers in dielectric liquids. WebMeek criterion As mentioned above, the formation of the streamer depends directly on the charge of the electron avalanche’s head part. That is, when the space charge increases and the electric field distortion is strengthened to a certain extent, enough photoionization will occur in space which leads to the formation of the streamer.
