摘      要：More and more applications of ZnO arrester in electrical system experienced more *** thing,that is still under some investigation,is the effect of multiple lightning strike to the performance of ZnO *** we know,the design of ZnO arrester for transmission system and for distribution system differs in the point of view of the number of ZnO *** system,due to its higher nominal voltage than distribution system,has more numbers of ZnO blocks inside an arrester *** term of the current rating of an arrester,it is found that there is some different value of the current *** current rating of an arrester installed closer to electrical substation is higher than that of some further away from the *** the respond of a lightning impulse strike,the arrester will let a high value of impulse current *** tends to heat the ZnO material of the *** the number of impulse strike is quite high then it may give the effect to the change of the arrester *** condition will endanger the equipment that is protected by the arrester from lightning *** this research,the scope of work is limited to making an impulse current generator toward to one having 8/20 μs *** kind of impulse current wave-shape is the one that is used for studying the performance of ZnO *** effect of the inductance and capacitance of the impulse current generator were also studied.A 10 fused cut out was blown by an impulse having 10321 A of 17.8/37.8 μs.A ZnO arrester block brokendown/allowed large value of current :10982 A flowing under the voltage of 10.5
