An analysis on properties of mechanical fatigue and solid insulation during aging process should be made to reveal which ones we have not found in previous studies. Especially, the initiation and growth of electrical trees and mechanical fatigue are extremely similar. In this paper, a detailed comparison is made according to the theory of electrical trees(More)
The 3D shape of radar beams is drawn by direct volume rendering (DVR) algorithm based on 3D texture. Two procedures based on graphical processing unit (GPU) are explored to optimize the algorithm. In order to probe into the internal details of radar beams, three volume clipping methods are proposed, geometry-guided clipping, is surface DVR and exploded view(More)
In actual operation, the shielding failure rate of UHV transmission line is much higher than that in simulation, so it is crucial to study the lightning shielding performance by experimental research. The testing UHV transmission line model is scaled down in the ratio of 12.5 which is relatively large comparing to other testing models. Two kinds of negative(More)
Inrush current simulation plays an important role in many tasks of the power system, such as power transformer protection. However, the accuracy of the inrush current simulation can hardly be ensured. In this paper, a Jiles–Atherton (J–A) theory based model is proposed to simulate the inrush current of power transformers. The characteristics of the inrush(More)
