In order to study more effectively the power overhead line lightning performance differences in different terrain, this paper, firstly building statistical model of regional lightning, studying statistical distribution of the number of regional lightning method. Then use this method, analyze statistically lightning on three types of terrain on the Pearl River Delta of 10 years based on lightning location...
The accurate model of cable termination is set up. Further more, different deep of water in silicone oil are also be consider to the model, which are 2 mm, 3 mm, 5 mm. In order to simulate the electric field of the water in silicone oil of cable termination, the finite element analysis method is used. And the results of the analysis are also illustrated. In the experiments, termination with water...
The accurate model of the pre-fabricated HV stress cone of cable termination is set up. Further more, any of the weaknesses are also be consider to the model, such as the interface of the stress cone and the cable, the distortion of the cable termination by the torsion outside, and so on. In order to simulate the electric field of the pre-fabricated HV stress cone of cable termination, the finite...
