Study of ZnO arrester model for steep front wave

Measurements were performed to get the response of arrester block to steep front impulse current(ll2p sec), 4/10psec impulse current and standard impulse (SDOpsec). AʹS the steep front wave response model, the conventional model, lEEE model, and nonlinear inductance model have been studied. The method of building arrester block model was explained in this paper. The nonlinear inductance model proposed in this paper has accuracy with about 1% error in calculations of steep front impulse in block model study. This model can be built easily and simply.
