This paper studies the performance of an MV underground cable due to a nearby lightning discharge. The simulation is made with Finite Element Method (FEM). The effects of lightning stroke location, resistivity of the soil and underground cable configurations are considered. The results of the numerical computation show how electric field intensity and potential distribution vary with the factors mentioned...
In this paper, some key factors of the insulation design of DC cable relating to its electric field intensity distribution, insulation characteristics and selection of insulation material etc. was researched. The DC cable characteristics relation between insulation resistivity and temperature, especially effect of space charge electric field intensity on the insulation design and selection of semiconductor...
According to simulating test on the model sample by using high speed digital camera (10000 fps) and combining with finite elements analysis software, this paper studies the discharge process of discrete water droplets on the hydrophobic surface in the non-uniform electric field ( needle-board electrodes ) and computes electric field intensity along hydrophobic surface. The results show that the development...
