Study on Applicability of Simulation Model of Metal Oxide Arrester Under Different Impulse Current Waves
In this paper,the experimental study of residual voltage and energy characteristic of resistor disc for sever-al types of representative metal oxide arresters are performed at such four types impulse current waves as 30/60、8/20、4/10、1/5 μs,and the application of IEEE,CIGRE,Pinceti and MWR simulation models of arrester is analyzed.The results show that the residual voltage simulation of IEEE model is weak at 1/5 μs and steep wave current with am-plitude<10 kA and the energy simulation under four types of impulse current waves are also weak.The residual volt-age simulation of CIGRE model is weak at 1/5 μs and steep wave current with amplitude>5 kA,can simulate well the energy characteristic of arrester under four types of impulse current waves.The Pinceti and the MWR models can sim-ulate the residual voltage characteristics of arrester under the four types of impulse current waves.The energy simula-tion of Pinceti model is weak at 30/60 μs and the switching impulse current wave with amplitude<1 kA,and the ener-gy simulation of the MWR model is weak at 1/5 μs and steep wave current with amplitude>5 kA is weak.The study conclusion in this paper can provide reference for model selection and optimization of MOV simulation under differ-ent operating conditions.
