Electrical discharge phenomena from a grounded electrode located in a charged particle cloud have been investigated. Soil conditioning particles charged by corona charging were blown to form a space charge cloud. A grounded sphere electrode was placed at the center of the charged cloud to produce an electrical discharge. A positive pulse discharge extended from the sphere electrode toward the charged cloud with a strong luminescence. A brushlike streamer with a maximum length of 170 mm appeared at an interval of 30 ms. The maximum pulse height of the discharge was 2.4 A. The distribution of the electric field around the sphere electrode was obtained from field analysis using a concentric spherical model. It was found that the magnitude of the discharge depends on the radius of the grounded electrode and the size and charge density of the clouds. © 2001 Scripta Technica, Electr Eng Jpn, 136(4): 7–14, 2001
