000000415 520__ $$aModelling of MOA is necessary for many reasons and a considerable progress in this field has been made. It is very difficult to construct a general model of high voltage ZnO arrester in which we take into account a lot of factors, e.g. stray capacitance's, pollution, thermal processes, the response to fast transients and harmonics. Construction of a limited model for special purposes only seems to be a better idea. But even for such a limited, apparently simple task, a few models of medium voltage arrester in the low leakage region were proposed in literature.  A method to determine the lumped parameters of an equivalent circuit model is proposed. The method is  based on the published data which allows determination of the lumped parameters of an equivalent circuit model for the low leakage region.  For the high leakage region the parameters were chosen based on our own experiments.
