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.
