WebThe breakdown criterion in a uniform field electrode gap is Select one: O a. ayd=1 n O b. When a negative voltage is applied to a rod electrode, heating on the anode caused by field emission from the cathode plays a leading part as with the sphere-tosphere gap. High voltage impulses were used to investigate various possible factors influencing the prebreakdown current and breakdown in vacuum gaps of sphere-to-sphere and rod-to-plane.

Therefore, a combined breakdown criterion was proposed by introducing a geometrical parameter of the electrode system. In contrast, the breakdown in the non-uniform field gap (rod-to-plane) presents different phenomena depending on the polarity of the voltage applied. So, the electric field is nearly uniform, and BD occurs directly [25]. stressed electrode areas become much larger. 4421 #'\ Semester2, 2011 page 1 of 4 THE UNIVERSITY OF SYDNEY Faculty of Engineering 22.0 sts = 4 inches Needle size.

The breakdown voltages with the tip radius of the highly stressed electrode varying between 0.1 cm and 2 cm and the gap distance ranging from 1 cm to 5 cm were experimentally investigated, and the breakdown electric field distributions in inter-electrode gaps were analyzed by a finite element method. We arrive at the spark-breakdown criterion by framing it in terms of gain and instability conditions, whose relative importance are established from an analysis of the experimental breakdown characteristics and correlations with streamer behavior in short gaps. 4.6 out of 5 stars 13.
