Abstract
The Metal Oxide Varistors (MOV), of which the application features have been extensively researched, are widely used in the follow-up lightning protection in the low voltage power distribution system. However, to facilitate the design process, the simulation is always carried out to have preliminary study on the model selection of MOV, and therefore the MOV modeling becomes important. In this paper, based on the PSPICE, two characteristics of MOV, i.e., the V-A characteristic in the low current region and the response characteristic under fast impulses, are considered, for a circuit model to be translated into and further a MOV model under total current conditions given. What’s more, the 8/20μs impulse current generator and the square wave circuit with a rising edge of 2ns are utilized to have actual measurement, to a conclusion that the simulation results verify the feasibility of the model. This is of a certain application value to engineering design.
